Ishy -
I'm sorry to hear about your camera..
One thing to check on, and my wife told me this - after she called lost&found.. the CM at lost&found wasn't totally sure in the first place that they had actually found our camera - because there's *lots* of cameras that do look the same to people.. only after we had them 'turn on the camera' and look at a couple pictures (pics of the boys showed up and they described 'yes, there's this cute chinese kid') did we know that it was actually our camera
So, they might/might not have it even, and just not know it because all the camera's look the same.. if you know something specifically that distinguishes it (other than color, make).. the more you know (time, place, memory card size, things lost with it), it might help..
I know it may not help in your case, but i'll keep my fingers crossed for you
For all people - definetly 'label' your stuff somehow.. that's something I"ve learned for sure
