Look how the xbox fanboys are celebrating based on this one article.
Anywyas I agree with WiiStation360, this will be a useless storage medium just to drive up cost, the PS3 would've released for $399 and it would've probably be down to $199-$250 now if it wasn't for Blu Ray drive and all those initial losses.
We have seen extra space does offer an advantage, but enough to justify the costs? I don't think so, Pioneer has said that 400GB Blu Ray discs would play on PS3, let alone PS4 with 8 or 12 reading speeds. We have a handful of games that take 50GB disc, and a handful of games that take 50GB on a disc where you can really see the advantage there.
I expect the PS4 to be Blu Ray 8x or 12x reading speed and the 360 to either be Blu Ray or if they wanna gamble big time, HVD or DD only.
