Ok, aside from the standards which are already being worked upon (Hoth ground, Death Star), here are my 200 cents:
* Take, say, a city map like MosEspa, with the crowded streets, maze-like, etc. Have, say, 3 CPs in the city, with wide-open spaces all around (desert, fields, snow, or even water). Have at least one docking bay/port on the outskirts, and then plenty of fast vehicles (speeders, air vehicles, maybe a fighter or two) to get to another 3 CPs far outside the city. The vehicles will be difficult to use in town, but can be used for the remote sites, or just to skirt around the perimeter of town.
* Just one map where there's a SD or Corvette hovering (static) in the sky. Perhaps the guns aren't working, or there's something valuable on the ground the crew would never want to risk blowing up (fuel, innocent civilians, jedi crystals, school buses full of orphans and penguins, etc.). The ship can be to one end of the map, to limit how far escape pods can range, and perhaps whoever's up there gets a shuttle with which to actually fly down. The ground CPs can be (mostly) held by the other side.
* As for the space and infantry combined map -- boarding is fine, but it was possible in GC. I could be wrong on this, but I believe it was Luuri who made an ill-fated Kessel map. There was a SD up in space, and the skybox from the top was a planet far below, and the skybox from the ground was a sky (maybe with a tiny SD pictured up there). You flew down, through some clouds, and could then attack the ground. Now, this worked because in 1942, there was a ceiling above which flight wasn't controllable... so you'd drop down, but couldn't effectively fly back up. It was another place for the attacking force to bring in some fighters/bombers to deal with the 'bad guys' on the ground.
* What bugged me about Bespin in GC was the buildings. Let me say that I applaud the DevTeam for creating several new buildings with multiple levels indoor and outdoor. One of the biggest problems I had with 2142 is that nearly all structures could not be entered, and the few that could were 50 stories high, but only the bottom two were accessible. Sure, it keeps the battles on roughly the same plane, but it's not realistic. The Tatooine maps where you can not only hide in one-room alcoves but can also climb up to a balcony, or go even higher into a tower make things much more interesting. The GC Bespin map, aside from long, boring stairways, were made up of long, boring treks around monolithic buildings which may as well have been big rocks for all the gameplay effect they had. Granted, they were nice-looking and lore-accurate, but the buildings weren't fun.
* That said, I think something like the Tatooine buildings with Cloud City-type shapes and skins, with docking platforms around the sides (yes, like GC again) would be great. Instead of a very limited upper level, you could have two levels equally important -- with a couple CPs on each -- then you could have a lower-level carbon-freezing chamber and Ugnaught junkheap area, with the upper level being all pretty with walkways, sculptures, living quarters and dining rooms. Just a short flight of stairs, ladder, or ventilation tubes could connect the two levels. The docking areas would be platforms extending out from the structure, perhaps at a mid-level between the two, connected by half-stairways up and down from each level, bringing the two together. Add to this some cool stuff like Slave I or the Millennium Falcon (statics, most likely) on the platforms, and things start feeling extra lore specific.
This could be an infantry only map, or possibly an external, aerial aspect could be added (then again, that could be a whole different map). Overall, the feel I get for this one is like DC_Oil_Rigs, though with one big, huge oil rig in the middle. 
* Alternatively, perhaps a map like MosEspa with just a few wide streets connecting CPs (not directly, but with turns of course) on part (half?) of the map, would allow for more mixed weapons/vehicle possibilities with a narrower, cramped residential area up near places like Mos Eisley's market where speeders and Rontos can maneouver.
* As for Endor's Forest Moon map... I think it's great, except for one point. In the movie, the Rebels took the Bunker, but then lost it. I think the Push thing works great... up to a point. As it is, the map either gets bogged down at the central compound, or the Rebels take everything, and waste five minutes searching for the 3 missing snipers -- some of which think they can take back the first flags, somehow. Instead of revamping the whole thing, I'd make the last two CPs re-takable by the Imperials, and possibly add a second CP to the central compound. That'd certainly make the last area the climactic battle which held its own as counterpoint to the fleet battle in orbit...
* That said; in general, I love the maps with a little bit of everything. Give me infantry in trenches, hiding from tanks, and TIEs battling Airspeeders above. Lore-specific is fantastic, but don't sacrifice good gameplay over it. Make good maps, then search out settings that fit the layout description and can reasonably fit into some level of lore with the premise/story of the map. Even if it's EU, if it's a great map, people will play it. Even people who <gasp!> don't like Star Wars.
Oh, and thanks for the GONK!
