PS3 is a fine system. look at the capabilities and it's really crazy. if you are just looking at sales, it's not pretty for the PS3 because even though 600 bucks it's not that much considering what you are getting, the majority of the people generally don't want to spend that much money. and the games out for it right now is, well, weak. really weak.
i'm getting my PS3 either this week or next week and i think i'll only get Virtua Fighter 5 and resistance. those will do me good.
i'm thinking of selling my Wii. but i'm not sure if i want to part with it just yet.
