It appears that the DVD is popping up early at more than just Play.com. Jayjay writes that Laservisual.com have it in stock too.
“My Region 1 DVD arrived this morning!! It is a miracle I made it off the sofa and into work! I went straight to the November preview and the behind the scenes of TTT on Disc 2 and watched a couple of fave scenes on Disc 1.”
