Looks like this is confirmed with an August or Septemeber launch, but thus far only confirmed on Verizon. I swear if Microsoft was stupid enough to make this a Verizon exclusive, then the people making these decisions at Microsoft should be shot!
Engadget reports that they phone should launch by on "Verizon during the third quarter, or no later than the end of September" although our sources tell us that Microsoft Stores have a planning date of August 20 with a launch on the 21st. The off-contract, full price of the phone is listed at $610 with on-contract price most likely nearing $199. The name is also confirmed as"One (M8) for Windows" according to documents we have seen.
