I'm going to go out on a limb and say this is not gonna be WipEout. Nor is it even something for the PS4. My main reasons are as follows:

1) Motorstorm: Apocalypse needs a -lot- of work. I played the Alpha release at Eurogamer Expo, and I think it needs a bit of retooling. They're still developing it, given that the words 'Alpha Release' were in the corner throughout my playing, and if Sony wants to care for one of its' franchises, it'd be the one that's been with it since the release of the PS3.

2) WipEout is a pretty old game, lets' be honest. Coming up on its' third year... now why on earth would they release DLC for that old a game unless the userbase is big enough to warrant a good recall of money? As much as I would pay for it, and I'm sure anyone on these forums would, I don't know if the three hundred of us + however many yappy venom eliminator players there are would really constitute enough to make it up unless it's a high price.

3) Sony's just released the Move. That is a massive technological update, which I personally hate (think it's all dodgy) and provided support for 3D systems. Why would it be releasing a PS4 now, when it's sunk so much money into an existing console already? If the PS4 flounders, it'd be curtains for Sony. Yes, the 360 is showing better graphics right now, but is that really that big a reason to release a brand new console? Especially when you can boast your own motion control system and 3D support?

So I'm sorry guys, I don't buy it. They're looking for someone for Motorstorm: Apocalypse.
