Yesterday, GameTrailers TV host Geoff Keighley revealed that, according to his sources, the PlayStation 4 will employ some form of digital rights management when dealing with used games. Twitter took it upon themselves to show Sony how bad an idea this is.

My article on Monday about Respawn Entertainment's first post-Call of Duty game, a sci-fi multiplayer shooter, coming exclusively to the current and next-gen Xbox consoles, turned some heads. So did the part of the piece about Microsoft falling behind with their next-gen machine.

Let's all remember: We haven't seen the PlayStation 4 yet. Along with games that were purportedly running on the system specs, Sony's event last month only showed viewers the controller.

Among the bits of information dropped during last week's PlayStation 4 announcement was this from PS4 lead architect Mark Cerny, as he discussed the system's enhanced social features.

Ubisoft CEO Yves Guillemot likes the PlayStation 4. Otherwise he wouldn't have showed up at Sony's big PlayStation 4 event last week, right?

One of the oddest, most memorable parts of last night's PlayStation 4 announcement event wasn't a game or a piece of hardware. It was four dudes, standing still.

Last night, during the big PS4 conference, Sony brought Gaikai's David Perry on stage to deliver some lofty promises for the new gaming console.

Did you miss last night's big PlayStation 4 announcement? Want to watch a highlight reel that has the benefit of being both a lot shorter than the actual event and quite funny? VideoGamer's got you covered, with this "abridged version" of the event. I very much enjoyed this. Good show, guys.

Stemming fears of the always-online requirement still rumoured strongly for the next Xbox, a Sony PR rep confirmed to Kotaku that: "PS4 games will be playable without an Internet connection."

Sure, it was fun to watch yesterday's PlayStation 4 reveal from the comfort of your own home. But that was while it was going on. When it ended, the cameras cut away.

One of the surprises at tonight's PlayStation 4 reveal was the announcement that Blizzard's previously PC-only Diablo III will be coming to both PS4 and PS3.

More news from today's PlayStation 4 event: the ongoing tyranny of the polygon. No, but seriously though: here's Media Molecule on its latest project, which uses the move controller as a sculpting tool. It looks crazy cool for you creative types.

Destiny will be out for PlayStation 4, Activision announced today. Both the PS3 and PS4 versions will launch simultaneously.

Diablo 3 is coming to PlayStation 3 and PlayStation 4, Blizzard announced today. The console version will include new controls and a four-player single-screen co-op mode.

In a presentation by Ubisoft at the PlayStation 4 event, there was a little bit of talk about its upcoming title, Watch Dogs, which we reported as likely coming to next-gen consoles last week. Guess what: you'll be able to control all sorts of things, like traffic, and people's personal lives.

No real news yet, but Square Enix's Shinji Hashamoto took the stage at today's PS4 event to say the company is working on a Final Fantasy game and that we should "please be excited for E3 this year".

Sony showed off this list of developer logos at their PS4 press conference today, and it's got some exciting ones, from big to small, Activision to Spike Chunsoft.
