As a matter of fact, Microsoft already announced that IE9's rendering
engine would use GPU acceleration as much as possible (leveraging MS
Windows' DirectX technolgies) [1]. Some benchmarking of the platform
preview vs. IE8 show a more than welcome improve on performance [2].
Thus, it's not a matter of accelerating just <video>. UA vendors are
allowed to use any available technology, such as GPU processing, to
improve the user experience on all aspects; and IE9's approach will
benefit not only <video>, but everything that the browser renders (for
example, heavy JS-based animations may take huge profit from this).
I'm not a big fan of Microsoft's IE software, but I must concede that
the Redmond guys have taken a step on the right direction with this.
Especially having seen how IE8 was painfully slower than its older
siblings (IE6 and 7). I wouldn't be surprised if other browsers follow
