Namco X Capcom was one of the greatest fan services EVER. Throwing Sega into the mix just made things even more fan-service fulfilling. I just hope they put in Reiji and Xiaomu from NxC, because they are two original characters that I can say fit the game and were very fun to play as. Speaking of gameplay, it seems to take after the "sequels" to NxC that were on DS (and were spinoff titles to the Super Robot Taisen series). They were called Super Robot Taisen OG Saga: Endless Frontier and it's sequel Super Robot Taisen OG Saga: Endless Frontier Exceed.

Many MORE characters are to be announced, so if you happen to have a wish-list, chances are those characters will make it into the game.

I don't have any characters from Namco-Bandai that I can particularly think of that I'd like to be added(other than more Tales or Tekken characters), but if SEGA going to be part of this at all, I'll accept anything, ANYTHING from the Phantasy Star series(not necessarily a fan of PSU, but I'll take it). Since a Dead Rising movie theater is part of one of the locales, I wouldn't mind seeing Chuck Greene and Viewtiful Joe getting in on some undead film related action.

The gameplay looks alot like Mugen no Frontier EXCEED too, which is awesome, they added Reiji and Xiaomu in this game:

Speaking of Reiji and Xiaomu, it would be hawtness to throw in Saya if they add the other two.
