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.
