Thats pretty much a killer line up DJ! I dunno about onimusha character since there based on actual factual character in history . . . to some extent. I just dont think they should go there. Same with other game they did devil basara or something (cant be arsed to wiki the precise name right now)
EDIT: also just been brought to my attention it is super manly line up. I mean morigans titties are epic but not epic enough to carry the game. you need some more fems in there for sure. Ms Marvel? Black Cat? or on a lesser note Rogue and Storm.
I am really intrigued to see what the new graphics look like though. As it all looks very grim and I perfer the colour pallets of the Vs games which are a lot brighter and such. You can tell a lot by the character art for say a character like Dan

Marvel super vs Street fighter

Alpha 3

Alpha 3 Saikyo

Here he is in Marv vs Cap 2
This aint the best character to pick maybe but I am just saying I love my comics to be bright and colourfull and a bit camp. The background were pretty dull in MVC2 to, The worst being the brown clock stage. There ripping on the pirate ship (kotaku podcast) but that was one of the few stages which had significance to the actual 'plot' . There saying that they want to change the look. I just dont want my Ryu to look like anyone else other than Ryu becuase right now he looks like a moody mother fucker. Also what the fuck is up with hulk?! Just saying its all a bit to dark for me I hope they splurge with some colour. Becuase the colour pallets in the CPS2 Vs Games were/are fucking awesome. The look of Marvel VS Capcom3 is very very dark. Which i hope there not doing just to get people to stop compairing to to VsTat or Street fighter IV.
Also how awesome a team up would Dan hibiki and deadpool be?
