Sony Ericsson's Xperia X10 bound for AT&T?

A lot of info has been passed along recently on the Sony Ericsson Xperixa X10. The joint-venture's first Android device was the subject of a Press Event in Sweden and Phandroid was there to shoot some video to give us the feeling of being there. Also, the site notes that Sony Ericsson has made some changes to the Xperia X10's web page that shows that the device would have the following bands covered:

GSM/GPRS/EDGE 850/900/1800/1900
UMTS/HSPA 800/850/900/1700/1900/2100

At first blush, this looks favorable for both AT&T and T-Mobile. But the following line says that 900/1700 is not available for phones sold in the Americas. And then there was one. AT&T is the last carrier standing which points to a subsidized price for the Xperia X10, something that fans of the device had been hoping for since the first word came out about a phone named Rachael all those months ago.

Another interesting tidbit is that the X10 will have turn-by-turn navigation courtesy of  Wisepilot. Since the handset will not launch with Android 2.0, Google Navigation would be a no-show at the beginning, anyway. But when a 2.0 update is made available, will Xperia X10 owners still have Wisepilot or Google Navigation or will they get to choose which one they want on their device?
