The fact is Sony just has to produce a more "open" console than Microsoft and Nintendo, and it looks like they are doing that. Microsoft is a huge sell out, looking to control every aspect once again, and Nintendo have lost the plot completely.
There is a 4th possible contender that isn't owned by Sony, MS nor Nintendo. And personally I'm more excited about the Steambox that any of the other consoles (the ability to buy games once and play it on my laptop or games console depending on what room I'm in (or even if I'm at home at all) is very appealing.
