Not reeeeally delayed, a release date was never really announced... they probably don't want to release it and add loads of stuff, when they release it in Spring 2008 it'll have most of the things without needing to constantly update it.. I hope..
Talking about Home, the executive said as far as he was concerned, the release delay meant nothing had changed. He said, "We will still be opening in late November/Early December for general beta testing. So, the commercial start of Home will be pushed out later, but you will still get the experience this year."
