I went to GS to look for the face plate while getting my oil changed. They had sold out but they did thave the DS lite version:

And the PSP version
I got the Decepicon DS Lite kit. It was 20 bucks not really cheap but the art and game cases looked too cool to pass up. And I know that once the movie hits I may never find this again.
The craziest part is I own a DS Phat but not a lite. But now when I get one, I have a case for it.
I don't have a digital cam here so I can't show images of it. But the pictures are almost exactly the same as the 360 faceplate version.
It has 12 characters each with a front (robot mode pic) and back (vehicle) mode. So you get 24 images.
In the pack is: Soundwave, Scorponok, Starscream, Skywarp, Megatron, Sockwave, Brawl, Razorclaw, Bonecrusher, Barricade, Vortex, and Frenzy (blue Rumble)
I didn't know why they picked Barricade or Bonecrusher over say Devastator. But then I remembered Barricade & Bonecrusher are in the movie. So it kinda makes sense.
