You have two different gameplay styles, Tekken is 360 degrees of fighting and SF is not. If you make the game like SF Tekken fans will lose the ability to move left or right and would lose moves that were meant for 360 combat..unhappy Tekken Fans. If the game is made in SC/Tekken style those oh so awsome energy attacks would be evaded by a simple side step and the same would likely happen for ,super uppercuts, Bison's torpedo move (not sure if still does it), spinning kicks, etc...unhappy SF/capcom fans. So how would this work?

it still might be a rumor for all we know!

I hope there isn't a Tekken vs. Street Fighter.  Virtua Fighter vs. Tekken? Yes. Capcom vs. SNK 3? Absofreakinglutely. 

rumors say that there ill be 2 versions, 1 will be developed by CAPCOM with there traditional VS series and te other by namco using the SC4 or tekken scheme.

plus lets not forget that Street fighter has been in 3D* more tekken like* before with Street Fighter Alpha EX series

If it really exists, it will be just like every Capcom vs. game

really!? what isa it called

Its called Street Fighter Ex. It was designed to be more tekken/dead or alive like, go youtube it

Yeah but Street Fighter EX is an utter abomination and should be buried in the same landfill as all those old Atari E.T. cartridges.

What!?!?

I LOVED that game ;(
