They could but they almost certainly won't. The amount of work required would be huge.
Since Amazon's DRM format (azw) is based upon Mobipocket DRM, we can be fairly certain that the .azw books are also encrypted the same way - with a PID. They'd have to reissue a new Kindle firmware, and also change the internal Amazon server encryption code. Depending on how they did it, they'd have to re-issue all of the old books or make both PID methods work at the same time.
After they did all that, it'd take a tiny effort to make a new kindlepid.py that accounted for the new scheme.
They'd be much better served to use the new 'unbreakable' format that I keep hearing about, Topaz. They would honestly just be better served to get rid of DRM altogether. Because Topaz will be broken next, so will Topaz 2, Topaz 3....
