Windows 7 (next version of OS to come after Vista) is shrouded by tons of really unreliable gossip and confusing news on weird features. I think it had bothered someone there (at last) and they don't really want to end up with ugly where-is-that-stupid-WinFS-you-had-promised-us press like Vista.

damage press control blog because of past experience… Still it's very good to have a source of solid news on product that is very possibly going to make your computing experience paradise (or maybe hell) in few years.
