I quite like the news/rumor that the PS4 will record the last 15 minutes of gameplay which you can edit/share at your heart's content, I've had some one-in-a-million flukes in my time gaming that no one else will ever see.
Generally though... I can't stand new console releases. If you buy it too soon, you're gonna have "the old crappy, fat version" within 18 months. Plus I fear it'll lack compatibility for PS3 games. That's another 110 game cases consigned to the secure location under my bed, never to be seen again. Oh, and I despise fanboy wars, worst thing about gaming by far. People need to get a grip.
