Welcome to Android Central !
Some Verizon Xooms have already received their update, there's a rumor going around that they will all be upgraded by Friday.
If you don't mind hacking a bit check out the hacks forum for a method that will let you update manually, otherwise a little patience and you'll have it soon.
