That may be the case, but i can tell that Hoth ground is a much awaited map by a lot of people, for one because it would be the first with a wide and open landscape with vehicles making a difference, but i dont know how much other maps (those that are being worked on) fit that criteria. Right now, next to space, we have maps that are 80% infantry based (except Mos Espa in a certain mode with 2/3 ATST's). And well, Hoth being one of the biggest and known battles in the SW movies, you know the rest...
I hope that it will be completed on schedule so that it's in the next major release, you all work pretty fast, so maybe. Well, we all dont know how big the Hoth map is going to be or how much work needs to put into it, if its going to slip to R3, i can only guess that it's going to be a pretty awesome map, and atlast to see some good AT-AT's...
