I have been researching this.  I have talked with Microsoft support and they seem to think that Verizon will offer the update to Icon buyers.  They are very careful to never say that they know what Verizon will do or that they can in any way influence Verizon.  They noted that that Cyan was in testing, and they did not think that in testing would be stated if, in fact, it were not in testing.  So I am being patient.

Verizon would be foolish to not develop an alternative to Apple and Google, or eventually face great pressure to follow the dictates of these corporations at the expense of the Verizon network.
