Street Fighter 5 was a necessity, not a win.

PS4 will have plenty of other exclusive fighters, although perhaps not on that level, Guilty Gear is already on the list and so far Tekken 7 has only been announced for PS4.

Obvs SF5 is the big daddy of fighters tho. It is a big win.

 

Tekken is the bigger franchise however it's only currently been announced for arcades.

Tekken was bigger years back, but Street Fighter is much bigger today. Plus, Tekken is strongly PlayStation-aligned anyway. It may be exclusive. But, if it's not, it will still sell immensely more on the platform based on previous fan alignments.
