Vista's original codename, 'Longhorn', was an allusion to this plan: While Whistler and Blackcomb are large ski resorts in British Columbia, Longhorn is the name of a bar between the two mountains that Whistler's visitors pass to reach Blackcomb.
Microsoft originally expected to ship the new version sometime late in 2003 as a minor step between Windows XP (codenamed 'Whistler') and the next planned major release of Windows, code-named 'Blackcomb'.
