He obviously has no idea what he's talking about. 4K video in HEVC will have practically the same space demand as 1080p in AVC, and will easily fit in a standard 50GB bluray. No 100GB files necessary.

Yeah, this guy has a history of saying things that simply aren't true. He should stick to programming and let someone else talk to the media:
Despite the success of his games, both critical and financial, Molyneux has acquired a reputation for issuing over-enthusiastic descriptions of games under development, which are found to be somewhat less ambitious when released. This goes back to Black & White, though the most well-known case of this was with Fable, released in 2004 without many of the features talked about by Molyneux in press interviews during development. After the release, Molyneux publicly apologized for overhyping the game.
