@MazdaChris – Sony have confirmed that the PS4 WILL be backwards compatible through a cloud feature, allowing people to stream old games. You probably won’t be able to play games you currently own, which isn’t necessarily great, but that’s something every console has to deal with. Also, have you not been reading? They are clearly not ignoring tablets or other mainstream technology, they have already said that you will be able to other Sony tech, like laptops, phone, Vita and so I doubt they’d forget about a tablet.
I’d also like to add that this is all very early. This was the first official announcement of the PS4. Did everyone really expect that they would show all their cards this early, and leave nothing for the rest of the year, whilst their hype slowly dies down? It would have been absolutely foolish to do so. I believe that there is still more to come. More features and certainly more games.
My belief is that later in the year, they will announce more titles, which will be set for release for the PS4. The first game that comes to mind would be Uncharted 4. Uncharted 3 came out late 2011, with the previous iteration coming out in 2009. All signals would point to a new Uncharted later this year, releasing it with the PS4, which would be a major draw-in for many people, including myself.
And perhaps Gran Turismo 6? Sony need a great console for starters, which I believe they could have on their hands, but major titles will be what sells it, and Gran Turismo 6 could be one of them. In November, it will be 3 years since GT5 was released, which would be a little less time than between GT4 and GT5, but could well be on the cards.
InFamous: Second son has already been announced, which I am very excited for, and I wouldn’t be surprised to see Little Big Planet 3 make an appearance either. There are still plenty of announcements to come, with big games on the horizon.
