I got it from Wal-Mart at midnight. I'm watching the 'Beginnings' disc right now. Something that will surely be online for download. So don't worry about getting this version unless your really want it. It's just comic book panels with voice over on it. And yes Welker talks for Megatron in this, for those who want to know.
I think I plan on buying the HD-DVD add on for my 260 and thne go and get the high-def version. Time will tell, but if I do, Transformers will be the most I've ever spent on a single movie. $8 a ticket to see it 8 times in the theater is equal to $64 plusus the $22 for the regualr version DVD plus $150 for the add on, plus $30 for the high def version....$278 on one movie...........*barf* lol
