I doubt that, it's a 2 minute video, a full length (2 hours, in this case) 1080p HD Blu-ray film takes up about 1.85GB's. If it's bigger, it wouldn't be much bigger, to be fair. I never did say that my estimates were entirely accurate. Edit: To be honest, my estimations are incorrect, I can't be 100% accurate. But, I actually think, given that I needed to check a few things, the estimation would actually be smaller than what I said originally. Again, not 100% sure, and I never will be, unless Bungie says so themselves.
