Every title shown in the event was disappointing except Watch Dogs which was also running on PC .

The PS4 processor is also x86 (32 bit) and main stream Graphics card .
Bathesda : Not as huge change as it was back in 2005/2006 when current gen was out . This time it's all about sharing and staying connected .
I watched the entire show live , PS4 is not backward compatible it will play PS3 games via steaming from internet . Always online requirement during gameplay was never touched but Diablo 3 announcement for PS4 can be hint of it (Now we know why Diablo 3 was casual ).
But it was all expected . Almost every rumor was true .
