Well the idea wasnt for the benefit of games but for the media convenience.
I guess if you are interested in the PS3 games, then getting a ps3 is pretty much a no brainer, and that is regardless of the ps move (not gonna consider it much of a benefit until it really takes off, and i have the same stance on the kinect).
Slightly off topic: my time warner remote works great with my xbox. Will generic multi device remotes work with the PS3 too?
