The disk vendors have agreed to transition no later than 2011.  There
are definitely drives coming out with 4KB physical blocks before then.

There has been a lot of discussion of the merits of shipping 1-aligned
drives by default given that Vista and Windows 7 handle alignment
correctly.

I don't think there has been any firm decisions in IDEMA wrt. 0
vs. 1-aligned.  It may be up to each vendor's discretion, target market
segment, etc.
