We first caught wind of this yesterday, when @0mie tweeted:
all #Revolution #Play orders SHOULD start shipping Thursday night/Friday Morning :)
Today, one Droid Life reader confirmed the essiting info with the following screenshot:
Of course, it's possible - likely, even - that not all pre-ordered Xperia Plays have been shipped yet. Also note that while Droid Life's tipster was told that his parcel should arrive on May 23rd, customers who paid for overnight shipping may receive their devices sooner.
Regardless, this is serious cause for celebration for the millions of giant-thumbed smartphone geeks awaiting the Play with bated breath. So long as the phones don't get stolen before they hit their destinations, that is.
