Funny Ed... As of last weekend I'm in exactly the same boat you are
The LCD screen for my HTC Wizard (Cingular 8125... Three years old now) was cracked at a baseball game, and finally gave out completely on Thursday. So I'm on a Motorola v400 now, and my friend is going to loan me his old TMobile Wing to tide me until this comes out. So this news is equally devastating to me.
As a side note, I noticed that the TMobile Snap, which was supposed to be released on July 1st, according to the same source that reported a July 22nd date for the Wing II, has also not been released yet. So I'm thinking this is probably more along the lines of some sort of shipment delay or something... Some event that would effect two models.
