I really need to replace my old vita. I bought it 2th hand and while it still runs, I don’t think it has much longer ... and I have so many games for the vita :p

It really is a great handheld for unique games. However I’m not sure which version to buy. Of course the old ones have the better screen, but I would love to see my vita a bit faster. Do any of the newer models have improvements? I would be willing to import from Japan.
