Sony Ericsson Z660i rumor or real?

The rumor about the new ultra-slim clamshell, called Z660i, started about a week ago. Now Michael, the owner of USEB has received an interesting picture, which shows how the Z660i looks when it's open. The picture is definitely made with Photoshop, but if you compare it to this photo, you can see that the keypad looks quite similar.

In my opinion the phone looks pretty stylish, but I'm not so sure about the keypad. It reminds me of Motorola's handsets, which I didn't liked. I hope this works better! Anyways, looks like the phone will have stainless steel finish!
I think there's definitely room for this kind of clamshell in Sony Ericsson's line-up, so I obviously hope this isn't just a rumor.
