Actually I saw TI's release announcement of that on Twitter today.

It looks like it's aimed more as a camera/camcorder processor than a media 
CPU. I've looked at the datasheet and yes, this thing looks very, very 
impressive. If the hardware coprocessors are not locked behind some kind of 
NDA firewall which would prevent active Linux development of these subsystems, 
I would be very happy indeed.

Sadly, neither of the coprocessors is listed in the peripheral document list, 
and you see nothing of h.264 nor hardware motion compensation listed in 
anything but the feature list. They may be keeping information under less 
restrictive wraps, but my experience has shown that if the info's not just out 
there, then it's under NDA, which kills any OSS development.

The six month lead time is a bit of a buzzkill as well.
