Well Sony and Microsoft have often say they wont show this and that in the near future and most of the times they lie. If Sony say they will anounce a Playstation 4 this e3 than this will catch up potential ps3 buyers.
And if they really dont show anything at e3 that wont mean they cant show anything at gamescom and tokio game show.
I think we will see some x box 720 and ps4 anouncement this year and a realease in 2013.
