Street Fighter 5 was a necessity, not a 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. 

I'll hear none of it (I know you are right as relaunch of SF in the new style was so successful it was a little silly, it accounts for near 20% of all SF sales).

Yet surely then Tekken being more Playstation aligned means Tekken was the franchise Sony needed to go for not SF.
