I want Capcom vs Rare Ltd
Capcom’s rosters - Ryu, Chun li, Ken, Dante, Lady, Jill Valentine, Lord Raptor, Felicia, Megaman X and Bass.
Rare Ltd’s rosters - Fulgore, Hisako, Cinder, Orchid, Zitz, Dark Queen, Conker, Joanna Dark, Banjo and Jetpack
Capcom’s Final Boss - Oni
Rare Ltd’s Final Boss - Eyedol
I think capcom should do a marvel version of injustice
They can’t due Marvel retiring them the license of their products
That’s the reason they had to retire some games from xbox live/psn store and the lack of content update for MvC 3
I think marvel should have a version of injustice, they’ve a lot of awesome power set characters
Brilliant comeback XDDDD
I’d personally LOVE to see a Capcom Vs Sega game. Plenty of characters that could be used on either side:
Capcom:
Ryu (Street Fighter)
Batsu (Rival Schools: United by Fate)
Strider Hiryu (Strider)
Dante (Devil May Cry series)
Samanosuke (Onimusha)
Felicia (Darkstalkers)
The Tyrant (Resident Evil Series)
Hagger (Final Fight Series)
Arthur (Ghosts N Goblins)
Mega Man (Mega Man Series)
Regina (Dino Crisis)
Viewtiful Joe (Viewtiful Joe Series)
Frank West (Dead Rising)
Rei (Breath of Fire 3)
Phoenix Wright (Phoenix Wright: Ace Attorney)
Sega:
Sonic (Sonic the Hedgehog)
Sarah Bryant (Virtua Fighter)
Joe Musashi (Shinobi)
Vyse (Skies of Arcadia)
Vectorman (Vectorman series)
Raikoh (Otogi)
Ulala (Space Channel 5)
Blaze (Streets of Rage)
Larson (Eternal Champions)
Nights (Nights into Dreams)
Raxel (Fighting Vipers)
Gilius Thunderhead (Golden Axe)
Gunstar Red (Gunstar Heroes)
Beat (Jet Grind Radio)
Ryu Hazuki (Shenmue)
Sub Bosses:
Death Adder (Golden Axe)
M. Bison (Street Fighter)
Final Bosses: Dr. Wiley (Mega Man) and Dr. Robotnik (Sonic the Hedgehog).
All four are hidden, unlockable characters.
And what game wouldn’t be complete without DLC characters?
Juri (Street Fighter)
Wesker (Resident Evil)
Luka (Lost Planet)
Ax Battler (Golden Axe)
Kage Maru (Virtua Fighter)
Ash (Phantasy Star Online)
I would play the absolute shizz out of that game. 
Oh I forget! I should add Capcom vs Rare Ltd final boss!
I don’t want Rare vs. Capcom, I’d prefer an all-Rareware/Microsoft fighter similar to Power Stone.
Likewise, Capcom could should do their own all-star fighting game where they don’t crossover with anybody but themselves. It would enable them to make the game they always wanted and patch it however they wanted.
Oh yeah, I 'd also love to see a Street Fighter X Final Fantasy game. I know that sounds weird, but it’s not like characters don’t “battle” in FF titles. Plus they there are summons, limit-break type moves, elemental magic and a bunch of stuff that could give each character their own style. I’d want to see:
Street Fighter:
Ryu
Geki
Adon
Ken
Chun Li
Blanka
Zangief
Sagat
M. Bison
Dee Jay
Cammy
Akuma
Charlie
Rose
Rolento
Ibuki
Yun
Alex
Doctrine Dark
Juri
Gouken
Necalli
Final Fantasy:
Warrior (Final Fantasy I)
Leonhart (Final Fantasy II)
Ingus (Final Fantasy III)
Refia (Final Fantasy III)
Cecil (Final Fantasy IV)
Kain (Final Fantasy IV)
Lenna (Final Fantasy V)
Galuf (Final Fantasy V)
Sabin (Final Fantasy VI)
Shadow (Final Fantasy VI)
Cloud (Final Fantasy VII)
Tifa (Final Fantasy VII)
Barrett (Final Fantasy VII)
Squall (Final Fantasy VIII)
Rinoa (Final Fantasy VIII)
Zidane (Final Fantasy IX)
Vivi (Final Fantasy IX)
Rikku (Final Fantasy X)
Kimahri (Final Fantasy X)
Vaan (Final Fantasy XII)
Lightning (Final Fantasy XIII)
Ramza (Final Fantasy Tactics)
Unlockable Sub-bosses: Sephiroth & Kefka (FF) & Seth and Shin Akuma (SF)
Unplayable Final Bosss Golbez (FF) & Gill (SF)
For Ultimate Street Fighter X Final Fantasy, Add:
Gen
E. Honda
Vega
Dhalsim
Fei Long
Birdie
Elena
C. Viper
Poison
Thief (Final Fantasy I)
Josef (Final Fantasy II)
Terra (Final Fantasy VI)
Vincent (Final Fantasy VII)
Steiner (Final Fantasy IX)
Tidus (Final Fantasy X)
Auron (Final Fantasy X)
Ashe (Final Fantasy XII)
Vanille (Final Fantasy XIII)
I just want Power Stone 3. 
But yeah, an all Rare/MS fighter would be awesome. So would an all Capcom fighter. I’d buy both of those, for sure.
Yeah, Capcom vs Rare would be awesome but need more fighter.
For KI Specifically I’d Like a crossover with Soul Calibur KI has a lot of weapon Characters (Hisako, Spinal. Maya, Jago, Tusk, Thunder, Kim Wu and Sadira) and a lot of the Modern characters can easily be redesigned into a fantasy types heck Fulgore can easily be made into an undead Knight, Orchid a Bakeneko, Arch Angel Aria. the cast is just works
Rare vs Capcom would be fun too Zitz + Morgan would be my team
THAT WILL BE VERY AWSEOME! Soul Calibur 2 gamecube is my favorite of the all time.
There is only one game that would matter, for balance’s sake. It’d be Cyber-Akuma vs Shadow Jago.
All others would bow before their might.
I’d like to say I’m gonna miss those games BUT I feel MvC2 was already pushing the roster size and mechanics into the extreme sake for the sake of. MvC3 is just silly, for me.
I want xmen next dimension 2
I’m still waiting for Capcom vs SNK 3 
I don’t think will there be Capcom vs SNK 3. sorry bro
