then patent the idea, usually it would be the other way around
especially so close to E3 as well, unless this patent was filed a while ago in which case it would be quite plausable.
The second part of your post I don't agree. Sony basically admitted defeat and failure with the PSPGo calling it "market research" of what customers wanted in a portable handheld game device. Basically at the cost of those who bought a PSPGo, Sony used them as gineau pigs to gauge the responses of what people actually wanted!

and so while it IS arrogant of Sony to release a PSP2 after a year of a PSP model, it would seem that the latest revision Sony released was merely an expensive marketing questionnairre for the features of the next version of PSP.
i agree with the first statement that Sony probably does patent a new product idea everyday (I don't check), but i doubt that Sony would make a prototype product and
