PS Vita compatibility and support
The PS Vita has already launched in Japan and is set to hit our shores very soon indeed. Sony made a big deal about PS3 compatibility with the PSP, a feature that was underused and often pointless when actually implemented. Seeing the Vita work properly with the PS4 then should be a real focus for Sony. Both devices seem to have a huge amount of potential, and being able to use a Vita as an extra controller would be infinitely practical and pretty cool if developers learn to use it right. Make it happen Sony.
A bigger hard drive as standard
In the age of HD media and large scale downloads, 60GB is never enough. Sure, you can always replace your PS3 hard drive if it really begins to tick you off, but I expect the PS4 to cater to my needs a bit better than that. It will not be enough to just be a “good” sized hard drive. Sony will have to future proof the PS4 by giving us at least 1TB, if not more. Considering the continually falling costs of memory, this shouldn’t be too big an ask.
Though I got my PS3 long before the delights of the slim model, I was still just a little too late to get one with backwards compatibility; and it annoyed the crap out of me. The biggest issue is running a PS2 in standard definition through an HD TV. It makes even the better games of that generation look like ass, and the space saving elements of backwards compatibility speak for themselves. Bring it back Sony. You can say that people aren’t interested in playing classic games, but they just are, so stop kidding yourselves.
