There's some interesting PSP 2 rumours of Slashgear today. It seems Sony's second hand-held gaming device might be ditching the UMD disk format ande becomgin a 'fully digital online device'. So does that mean games will be bought and downloaded on-line via some sort of app-store like system?

I’ve been (for a long time now) calling on Sony to move with the times. I love the PSP, I just wish they’d learn from the mistakes and move forward. I’m really tired of new versions being baby steps, or more color changes. I can’t reveal my sources, but you can be certain there’s no UMD, which means fully digital online device, and you know I know people" David Perry
