Cases for the Iphone 3Gs

This might be a really silly question, but does anyone see any statement saying that the new phone shape is simlar to the 3G? I read through the specs, the dimensions are the same, but i just want to make sure that the camera isn't moved or anything? I want to order a new case before my phone comes in, but i don't want to order the wrong thing, you know how they always designate if its for the 3G vs the original iphone. It sure looks like everything is in the same place as the 3G, but any reassurance would be greatly appreciated. Thanks
