Sony Ericsson K750 / W800 / D750 / W700

This phone looks like it has it all !!! If this phone is released, where do you buy it? And what carrier will it work on. I hope it is cingular. It looks like the t637. But that doesn't always mean that they will carry the newer version of the same phone. You would think that the carriers would listen to what customers say on these forums. And sell and carry the higher end phones like this one.
thanks to anyone with a reply to clear this up to me.
