They have other stuf they can "announce".
4K support, now that they presented a $700 player at NAB it's obvious that they could present the PS4 as a 4K player, Console and everything else machine for only 399,- and HDMI 2.0 (super deep color?
)
Not as big as Blu-Ray nor important but still something that would sell to the avs crowd.
They didn't really reveal a lot about the controller, there is more to be had there.
PS++? Final specs? Final look? Price? Digital Market for used Digital Purchases? PS1+PS2 BC
So far i am satisfied, price doesn't matter that much to me. I just need Microsoft to step up to the plate and not do anything stupid so i can get a 720 from launch, perfect console year!
