Why did Microsoft call Longhorn Windows Vista?

BetaNews asked Microsoft why they called their next-generation operating system, previously known as Longhorn, Windows Vista. They were told Microsoft feels the new version of Windows deserves a name that is more representative of what it specifically brings to customers. Here's the explanation:

"Today, we live in a world of 'more' -- more information, more ways to communicate, more things to do, more opportunities -- and at the same time, more responsibilities. Increasingly, we all turn to our PCs to help us with that," a Microsoft spokesperson said. "At the end of the day, what you're after is a way to break through all the clutter to focus on what you want to focus on, what you need to do. What you're trying to get to is your own personal Vista -- whether that is trying to organize photos, or trying to find a file or trying to connect and collaborate with a number of people electronically."

Actually I still prefer software with version numbers or years as they are way more convenient. I wonder what kind of marketing talk Microsoft will invent for the next-next-generation of Windows. Will it be called Windows Vista 2? Or should we expect another word, like AltaVista?
