What's Inside Sony's Mystery Box?

Sony's booth at TGS has a number of big glass display cases. One, however, is hidden. Its contents, a mystery. Whatever could it be?

Its contents will obviously be revealed following Sony's TGS presser. Our bet? Since it's in the PSP section, it'll be the "solution" for transferring your UMD games to the PSPgo.

That or another Gundam/Final Fantasy bundle.
