Oh, look. There's the Sony Ericsson Xperia X2a (the "a" points to the North American version) on the Sony Style Web site. It's still not available for purchase, but we saw it at CES running Windows Mobile 6.5.3, and CNET says its been told to expect launch this spring. We're not holding our breaths, given the lack of expediency given the X1, but we'll definitely be glad to see it when it comes.
