I have it on good authority from a representative at the ISO JTC1/SC27 meeting in Moscow earlier this month that the renaming of ISO 17799 to 27002 has been delayed until later this year, probably Q3 or Q4 2007. Although there are no changes to the content of the standard, ISO has to complete its formal process of explaining the name change to all the national standards bodies and gaining their acceptance. Oh, the joys of international standardization!
On a more positive note, progress is being made on the other ISO 2700* standards currently in the works. I will update the ISO27001security website accordingly when I have had a chance to get my head around the notes - early June probably. Head's too full right now.
