.. does anyone know when exactly will it be exiting the old preview video and entering the realm of the developers? :)

You mean when will you get realtime motion blur... and not that hacky blur of the previous frame... per-pixel blur based on the velocity of pixels on screen.

Project Offset has it and it is most likely implemented with a velocity buffer. See ATI's Bringing Hollywood To Realtime slides for an overview of it, but it's just what it sounds like; render the frame storing the screen space direction vector and distance from the near plane into the rgb. That buffer is then used to blur the screen.

Ah yes, I remember Project Offset... love that blur. Thanks for the info, just thought the one in the Legions demo was going to be in the next release of TGEA.

The one in Legions, i *think*, was a blur of the previous frame and not a velocity buffer implementation.

Should be a way to make it work using a full screen shader. Like the night vision resource.

Of course you'll need some horsepower but it's doable. They use it in BF2 with SM 2.0 hw.
