Seems more than just a bit suspect to me. Considering the number of post SP1 (hotfixes, patches) updates already amassing and what this might mean to someone doing a clean install of Windows 7 in say, oh I don't know, 2020. May have to block out a day or two on your calendar.
Maybe they'll revert back to their post service pack roll up packages circa Windows NT. Or, maybe this is another means of leading all the horses to the all new water that is Windows 8. A bit passive aggressive me thinks.
