Hasn't this been asked and answered a thousand times.
Release a system a year ahead $200 cheaper than its main competitor, building a stronger original fanbase. Create an increadible (pay to play, yet cheap) online experience. Soon younger crowd sees their friends with it, so they get it too after all it is cheaper and in HD.
Everybody has said most of these things which are obvious and hardly worth arguing about. Or maybe your like me and you had a PS3, but wanted to play Mass Effect, Gears and Halo on top of the great games Sony already puts out.
