PlayStation 4 Announcement Summary

And we're go!

- Things kick off with a typical E3-style PlayStation trailer.

- Andrew House takes to the stage, delivers lots of PR speak (House loves buzzwords!). Plugging Vita, PSN and the PlayStation brand in general.

- And now PlayStation 4 gets its first mention! Phew! House says presentation will take up two hours.

- PS4 will 'allow developers to explore' more flexible business models. Lots of focus on being developer-friendly.

- Lead system architect introduced - Mark Cerny - he's been working on this process for about five years. His focus here seems to be on interactivity and inter-connectivity.

- Specs: Supercharged PC architecture, X86 CPU, Enhanced PC GPU, 8GB Unified Memory, Local HDD.

- DualShock 4 shown off. Looks similar to (but better than) those leaks we've been seeing. There is indeed a touchscreen.

- Epic's Unreal Engine 4 shown off in real-time. Havok physics engine also demonstrated.

- Cerny introduces a trailer for the title he's been working on. It's called Knack.

- Background real-time downloading, simple gameplay video uploads, real time spectating of others' games, new friends network. In general much more integrated and personalised experience.

- Next speaker is up - David Perry, CEO of Gaikai. Naturally this means Gaikai cloud tech will be on PS4.

- You'll be able to play games straight away when browsing the PlayStation Store - instant access and experience.

- Facebook and USTREAM integrated.

- The 'Share' button on the PS4 controller will allow you to livestream your gameplay. Gamers will be given casting abilities.

- Remote play built into the PS4 (i.e. BUY A PS VITA!)

- Lots of PSN services touted - Netflix, Hulu, MLB, Crackle, Amazon, PS+ (naturally), and more.

- Gaikai backwards compatibility (streaming) confirmed. PS4 itself will not be BC however.

- These cloud services will be rolled out gradually.

- Now there's a montage trailer. Developers praising the ideas behind the PS4.

- Next speaker - Michael Denny. He in turn introduces Geurrilla Games (Killzone).

- Killzone Shadow Fall trailer. Lots of gif material here; very pretty and detailed (also - yey, colours!). Lots of gameplay footage.

- Next game trailer. It's a racer from Evolution Studios (of MotorStorm fame) - Drive Club. 'The game we've always wanted to make'. Team-based racing. Painstakingly detailed recreation of car models. And now we see some gameplay.

- Now a political broadcast on behalf of the Sony Freedom Party.

- It's actually a guy (Nate Fox?) talking about Sucker Punch's latest exclusive - Second Son - which is for the PS4. Seems to be about people who have superhuman abilities who are fighting for their freedom from oppressive government, or something along those lines (very next-gen inFAMOUS-y).

- Indie gaming now. Jonathan Blow (of Braid fame) is introduced. He's working on a new game - it's actually The Witness - for the PS4 (the word exclusive was used, though from the words used it suggests just timed).
