"Sony will follow in 2012, or maybe they will try to beat Micro and try to be first to market."
I don't think they will try to beat Microsoft to the market for two reasons. They have better games coming out over the next few years than the majority of what MS has, and they are going to become the hd console of choice in Japan and Asia especially with FFXIII exclusivity there. They will also probably still beat the 360 in Europe.
