Saw a few posts speculating that Xbox devs have been recruited to rewrite 60% of the Vista Code. Thought I'd answer: Not True. It's, at best, speculation with no demonstrable basis in fact. There aren’t any Xbox developers moving over to the Windows Vista team. Nope.

In fact, Vista is feature complete - meaning the code writing process is essentially over. The next phase of development focuses on security, testing and fit/finish – not writing new code. Vista is on track for business availability in November 2006 and consumer availability in January 2007.
