This is what Bill had to say
"bluray is a complete non-issue when it comes to multiplatform games they actually look worse on ps3 because 360 is the lead sku,
360 - Fable II, Halo 3, Infinite Undiscovery, Mass Effect, Mass Effect 2
PS3 - 3D Dot Heroes, Folklore, Valkyria Chronicles
mulitplatform games tend to be better on 360
i don't give a crap about sony's first party games
so if you're interested in those, then ps3 makes more sense, i have more 360 games than ps3 games, but again, that's because i usually go 360 when getting a multiplatform game, and i prefer MS' first party games (mostly just Lionhead and Fable)"
Bill Aurion "You know ya love him" has interesting insight, Still I'm on the fence between the two systems.
