Why?

A multiplatform game that was released on the 360 is now not coming to that ecosystem.

How does that make this not fair?

Capcom said they didn't have enough to make a next gen Street Fighter so I guess without Sony this game would exist.

Without Sony's support this game wouldn't have been made at all, Capcom said they were not in a position to make a next gen Street Fighter.  Tomb Raider was already being made and Microsoft just gave them extra money for exclusivity at the end.

The salt comments are like, the most annoying kind of comments on the site.

So it's terrible when Microsoft gets exclusive rights to Tomb Raider but it is perfectly fine when Sony does the same for Street Fighter?

All that aside, this is a great move for Sony, since the games have a very large fanbase. It will be interesting to see how the new game plays.

WTF!? This is just as bad as MS buying Tomb Raider.

But, this being Capcom, it won't stay "exclusive" for very long.

Very Insightful. These must be difficult times for Capcom.

Such a stupid exclusive, in what form exclusivity benefits a fighting game. Hope Sony didn't spend a penny on this.

Now Dragon's Dogma, that would greatly benefit from being exclusive, a game with great basic mechanics and so much promise but that needs some special dedication to pull it off.
