The original roadmap was to transition to 4KB sectors in 2006,
coinciding with the Vista release.

Given how long this has taken (we're now talking ~2011 for GA) it may
very well be that the alignment knobs will be unused because everybody
will be using Vista or 7 by then.

The plan does seem to have changed - WD's shipping 4k sector drives that are sane and require a drive jumper or tool for WinXP and old cloning utilities.
