I think you answered your own question - some of the options up for 
consideration in the PEP are *not* compatible with 2.x, so targeting Py3k 
makes for a freer discussion of the possibilities.

If the result turns out to be backwards compatible, then we can retarget 
Python 2.6, but that's actually the case for *all* of the Py3k PEPs (even the 
backwards incompatible PEPs will likely have elements which can be 
incorporated into the 2.x series to ease the eventual transition).

Cheers,
Nick.
