Read the entire post -- the dyno numbers are at the rear wheels, which incurs a drag penalty, which means the numbers at the flywheel are x% higher, where x is anywhere between 10 and 20, depending on specifics.
That being said, it seems quite a few new cars coming out have higher numbers at the wheels than expected given their ratings. Perhaps the engineers have gotten really good at minimizing frictional losses in the drivetrain over the past few years? Maybe the "standard" 10-15% loss for a RWD is too high these days?

I want one

Umm, no -- SXRD is Sony's version of LCOS, which is entirely different from DLP. Doesn't take away from the fact that their picture quality (in the latest generations) is very, very nice.

Ooh, my nephew would love these.

No, it's not worth it here in Austin (unless you have a Tivo S3).
