While I have to stress this is really heresay (a rep's opinion doesn't count as official), this isn't completely unexpected given the relative age of the X1. But then again, it demonstrates that manufacturers aren't terribly keen on supporting their own WM devices for very long, something we've had to live with through the last ten years. Which is a shame, since the X1 isn't that dated, and I suspect the hardware is more than up to the demands of WM6.5.
