Could MK8, Bayo2 and X run on a PS3[60]

[curl-6]

X and Bayonetta 2, no.
X's massive detailed environments are almost certainly too much for PS360's mere 512MB of RAM, same goes for the detailed cityscapes in the background of the frantic action of the Bayoneta 2 E3 demo.

MK8 could probably be done on PS3/360 though.
