Development of Odyssey began alongside the consumer-based Neptune project in 1999 and was based on the Windows 2000 codebase. Due to high hardware requirements and because Odyssey and Neptune were built on the same codebase, Microsoft combined them to form a new product codenamed
Whistler, for efficiency. No builds or versions of Odyssey were ever leaked or released by Microsoft as the product never left the planning stage. Confidential documents from the
Comes vs. Microsoft case do state that Odyssey was indeed under development. ==See also==
