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. -- Martin K.
