While I myself cannot get the X, as I have had my original Droid since November, I'm helping my buddy find accessories for his upcoming purchase. I've been using Steinheil Crystal protector on mine with great success, so naturally I started looking for the same version for DX to recommend to him.
Then I found this (I don't think this has been posted yet, if it has, my apologies):
SGP Steinheil ULTRA CRYSTAL Screen Protector for MOTOROLA Droid X [Verizon]
I'm assuming it's out of stock because it has not been released yet, but I'm definitely telling my friend to hold out for this one. Thought I'd share with the other future DX users.
