Fanboys aside (i.e. ignoring every post above this one
), the volume and quality of games released on the 360 (BioShock, Halo 3, Mass Effect, Lost Odyssey) in 2007 were [far] superior to PS3s which was basically limited to Uncharted, the rest of which were unfortunately flops for the PS3 (ahem, Lair).
Whilst Blu-ray has won the battle I do not believe that this will particularly move many PS3s in the short term future as whilst the technology is great, it is not yet a 'must have' and in many households is still redundant technology. However, the fact that many of PS3's promised games which have unfaithfully been delayed are supposedly coming this year, any changes in units sold will not necessarily reflect Blu-ray's victory.
I dont think that people should be associating Blu-ray vs HD DVD as PS3 vs 360 as it's simply not true, how many 360 users have actually bought the HD DVD peripheral? I'm sure the answer is along the lines of 'little to none' yet people are still buying the 360.
