Saving the best for later is a standard ploy at expo conferences, and Sony didn't disappoint at E3, when after an hour of game demos and new PSP announcements it broke out its new motion controller.
At first it brought a few guffaws, looking like certain models of lady pleasuring device. But Dr Richard Marks and his side-kick were at pains to explain that this was just an engineering prototype and that the look would definitely change.
Still, standing against Microsoft's recently revealed Project Natal
(pron: "Naaaaytal" by us), it had a lot to compete with.
One thing that Sony's device has over Microsoft's, however, is a release date of 2010. Microsoft's is still wide open.
But the guffaws were soon silenced when the boffins began to show us their tech demo. The device which features a coloured illuminated ball on top of a WiiMote-like handle couples with PlayStation Eye to combine motion sensing with optical location detection. The result appears to be a motion controller without the delay that plagues the Wii controller and makes it so frustrating - particularly in gun games. Game modes can be changed using buttons on the controller which also change the colour of the ball.
We were shown the controller being used for writing, which was pixel perfect, for swordplay - again with amazing accuracy. Then the controller was used to reach into the scene and manipulate construction blocks. Finally, a pair of the controllers were used for both hands using a bow and arrow. Reaching over the shoulder enabled an arrow to be retrieved from the quiver, bringing it back to the front knocked the arrow, and then the amount the hand was pulled back controlled the draw - and the power of the shot. Again, pinpoint accuracy appeared to be the order of the day.
Wii deserves credit for popularising motion control. And Sony may have left its real entry into the arena too late - but it looks as if it has conquered the problems that have made motion control better suited to casual games up to the present. It even went as far as to say that it had created the motion controller for "real games".
Barring delays, PlayStation Motion Controller will hit stores in Spring 2010, we're told.
