While Sony is still accepting orders for the Windows Phone (at a healthy $599.99) the anticipated ship date seems to be moving backwards. Today the ship date is estimated at May 12, 2010 and yesterday, it was May 11, 2010; both a little off the mark from "on or about" April 29, 2010.
Could we be seeing a repeat of the X2a's predecessor the X1a? So far Sony has only missed the original date by a few weeks which really isn't a reason to panic. However, if the delay continues for months (as it did with the X1a) the X2a may be competing with the Windows Phone 7 release. And at $599, that could result in disaster for what appears to be a quality Windows Phone.
