It's the latest OXM I got it in yesterday... the disc includes a (short) video interview with Cliffy and a slightly longer video interview with one of the Engine design guys who's been with Epic since the beginning.
No new footage on the disc, the cliffy B interview has a few split second clips but they've got so many video effects layered on top of them it really just teases you.
The disc also has the video trailer that's been floating around for a while. I'd watched it many times before on my computer but it was nice to see it in HD on my projector/surround sound setup.
I CANT WAIT for this game
...and before you ask NO there arn't any good demos, It's got the Outfit and RR6. The only other decent video content is an interview with the Historical Director for BiA3, it's also got some Tomb Raider Gamer Pictures
Though I think it's got an Xbox 1 demo for the new Hitman, I could be wrong I don't really care about the Xbox 1 stuff.
