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.

H.265 is supposed to have been made with fast decoding in mind. Docomo has already demonstrated 4K 60fps on 3-4 software threads with Ivy Bridge.

Even beyond all that, there's no reason to do it in software, as 4K HEVC decoding on fixed silicon should be trivial. The only question is how much wafer space that would eat up and whether the corporate bean counters would allow it.
Good to know; I was expecting another ASP to AVC for CPU requirements. No doubt UVD4 or whatever AMD will call it will have no problem decoding it but I doubt they would have enough time to add it since HEVC's final draft.

Those games were over hyped. So, he promised more than he could deliver. With video he's saying file size is a big problem. So not the same situation at all.

Psst... this is Phil Molyneux.. not Peter!

Sony is still being secretive about its forthcoming "world's first" 4K movie download service, but it sounds like it will eventually work with the equally-mysterious PS4. That's the word according to Sony Electronics President and COO Phil Molyneux, who said "I promise you will not be disappointed" when asked if the service would support his company's new console.

Oops, I had no idea two people with such similar names would be in the same industry. I googled the last name and came to that Wiki page. Are they brothers?

Ultra-HD is only four times bigger than Full-HD, which means you can multiply the size of the video on a Blu-Ray disc by four and get a rough estimate of what Blu-Ray quality video would require for Ultra-HD. The problem with that? Who streams or even downloads full Blu-Ray quality video?

Honestly, I don't think this will be a problem.

What's the point of a 4K TV if you aren't getting the best quality possible? Besides, for people who can actually afford a 4K TV in the near future, acquiring the content will not be their biggest problem.

And, more importantly, a Blu-ray disc stores 50GB, but a movie absolutely does not take up that entire space. You're forgetting about all of the extras also included on a disc. An average 90 minute movie encoded at ~30Mbps H.264 AVC is only 20.25GB. Assume ~2x savings advantage for HEVC but 4x number of pixels means your average 4K movie encoded at 30Mbps HEVC should only take 40.5GB. (this is a worse case scenario though, 4x pixels does not mean 4x data).

Molyneux's numbers do show that they'll be using H.264 to start off with, and probably wait for the PS4 launch to switch to H.265 (either software or hardware decoding if available).
