A remodelled PS3 smaller and cooler would be a good start.
Everyone seems to think that the new hardware will be a laptop.
I think SONY will have totally misjudged E3 if that is the case.
Laptops are for the Consumer Electronics Show. E3 is about the games.
I think they may confirm Home's release date and show off some features but it looks like a lost cause for the SONY boys at this years handbag fight.
