Photoshop has nothing to do with it.
The swirls were added using photoshop, but they were added to the final picture that was taken of the iPod (to protect his name and serial), that much is clear from looking at the pixels.
Q1. Is it possible that Apple can add these new transitions, effects and Tetris to the iPod?
A1. Yes.
For those of you who doubt this, take a look at the avi's on
this page for an example of an iPod displaying a 3D rotating cube, (both shaded and in wire frame), and playing tetris, chess, tic-tac-toe and a couple of other games.
Q2. Could the pic's that this guy has posted be fake?
A2. Yes, they could be faked easily.
Q3. How can we find out the truth?
A3. The only way we'll ever know if they are fake or not, is if the guy posts some video clips of his iPod. or he extracts the firmware and post's it online so that foolish people like myself can try it out, or we wait for Software Update to deliver the goods.
(Yes video can be faked, but if the iPod is in his hand and shaking slightly, it's soo much harder to fake that either we'd notice with a little inspection, or he probably wouldn't bother to take the time and energy.
I personally hope he leaks the firmware, cause that'll give me a few days of fun while I tear it apart.
