How I feel:
Orgus - eh, this games Dunbine.  Small, plain unit.  Will be boring to play ass but going by SRW, the story is alright.
Zeta - NEXT-GEN THE-O 
 
CCA - NEXT-GEN Nu 

Crossbone - looks sick.  Will be great to play as
SEED-D - well, since they took out G, it'll be the fun physical fighter to replace God Gundam
Overman - ehhhh, was just ok in ACE3
FMP - lol, wtf.  I like FMP a lot, but the mecha are tiny plain guys that can't even fly.  I don't even understand how this will work.  Regardless these units are gonna be zzzzzzz to play as
Geass - lollolololol, dumb shitty designs but they are so overpowered ridiculous that they might be fun to play as like the SEED units in ACE3
Aquarion - FUCK YEAH.  Will be like the Shin Getter from ACE3.  Multiple forms, awesome super attacks.  PUNCHING PEOPLE TO THE MOON
Macross Zero - cool, but all the macross ships play the same and the plane controls are :\
Macross Frontier - same
Overall a decent roster.  Some potential greats, a lot of middleground solid units, and some boring small units.  I just wonder if it'll be arcade-y like ACE3 or story/action-sim like ACE1/2, I didn't care for ACE3 as much.  Also it would be cool if it had decent online with coop & vs.  But since it's a Japanese game not coming to the US, I dunno how much they will bother with online options.  Online gaming in Japan is still pretty niche.
