Yeah, this can be true for some games. God of War 2 released AFTER the PS3 had launched, and it sold well.
However I'm not so sure of the selling power of Fuse. It looks like a re-imagined Resistance. While Resistance was never bad, it just never had that little extra "oomph" that made it a must have.
