Here's what I was shown:

Motorstorm 2 is due out in time for Christmas and moves the action away from the desert locale of the original. Gamers will be able to race around a lush island environment, full of interactive vegetation.

The game will feature four-player split-screen action, righting one of the obvious failings of the first game.

The title is some months away from completion but the game's engine looked rock solid and the graphics were as impressive as one would expect from one of the best-looking racing franchises.

Resistance Fall of Man was a bit of a disappointment when it was released. The game promised much but suffered from a lack of originality and flat game design. The world the designers had created was interesting but playing in it felt dull.

So what will Resistance 2 offer? I was shown only a trailer but it's clear developers Insomniac want to make a statement. Online the game will host 60 players simultaneously. It screams epic and tellingly it concludes with the line: "You haven't seen what we are truly capable of."

So what else was I shown? Well, I was shown a trailer for a game not due out till 2009 but was sworn to absolute secrecy. Apparently, Sony just wanted to give a glimpse of what the console will be capable of.

In fact, the game is such a secret that when I mentioned the game to Phil Harrison last week he was unsure at first whether even to admit the title existed. When I explained I had been shown it under strict Non Disclosure Agreement terms he looked relieved.

I don't mean to be a tease - all I can say is that I was left speechless. If the footage I was shown truly is "in game", as told to me by the Sony PR people, then we could be on the brink of a step change in what games consoles are capable of in terms of story-telling and immersion.

And there I'll leave it. Feel free to speculate on what I was shown. I cannot, of course, confirm or deny what it was....
