I have been waiting to buy a ps3, happily gaming on my XBOX 360 and Wii. 

I want to get one, but was wondering if there are any solid reasons, games, etc. that would put me over the edge in ivesting in one rather than buying something else of value at Best Buy.  MGS made me buy a ps2 over xbox back in the day, and Resident Evil 5 is something I want to play, but what of the other games and PSN items...is it a must buy today!!!
