With Windows Vista nearing its first release candidate in preparation for a final launch early next year, Microsoft is providing more details about possible upgrade paths. Of note: Windows 2000 cannot be upgraded to Vista.
While Windows 2000 Professional customers may purchase a cheaper "upgrade" copy of Microsoft next-generation operating system, Windows Vista must be "clean installed," which means users will need to back up their files and data manually and then copy everything into place. Applications will also need to be re-installed.
The x64 version of Windows XP will also have the same requirement. Although the final release of Vista will include both 32-bit and 64-bit iterations of the OS, Microsoft has not designed an upgrade path for the current x64 release.
Windows XP Professional, meanwhile, can be upgraded only to the Business and Ultimate editions of Windows Vista. This is due tof eatures built into XP Pro not being added to the Home Basic and Home Premium SKUs of Vista.

*I can't get smilies to work?
I hear you, but having this many variants is crazy. How many are there now?
Basic, Home, Pro, Pro 64, ultimate, media, tablet pc, ... Im missing a few. They differ in subtle ways, like having different backup/recovery tools.
I think they aren't sure what to do with the media center and tablet pc stuff honestly. They should probably just throw everything together for the consumer: Basic and Ultimate. Then for the developer: Business (get rid of "professional"
Basic, Home, Pro and Ultimate are the only versions users will actually be concerned with, the rest of these versions are for more specialised purposes such as small business, servers, tablet PC's ect. Basically only a subset of the actual Vista releases will be applicable to home users.
Of those releases for the "average user" who doesnt require specialised functionality you can then drop Pro and ultimate as they arent intended for them leaving only basic or home editions. I seriously doubt you will see as many editions available in stores as you seem to suggest. It's possible that something like basic will only be available OEM too, kind of like Windows XP N. I duno but.
Although I havent read this anywhere, seeing as how EVERY version of windoes comes on the same disk and functionality is unlocked based on the key, I wonder if the 64 and 32 bit distinctions will only be made at install time, ie they wont be boxed as individual products or priced differently. I couldnt say but it would seem to be a logical move IMHO.
OEM's will also gravitate towards a single release or two max probably, most likely one being home and the other being either pro or ultimate.

Your close, the versions are as follows: Starter, Home Basic, Home Premium, Business, Enterprise and Ultimate. The Tablet PC and MCE fuctionality are built into some of the versions of Vista (I know Home Premium and Ultimate have them, not sure on the other versions though) Here is the link if you don't believe me
EDIT: As for the 64-bit editions, I'm assuming there you can get 32-bit or 64-bit versions of all the Vista editions with the exclusion of Starter of cause, but I could be wrong about that as I'm not sure.
EDIT2: I also beleive the install CD is the same for all versions so it doesn't matter if you buy Starter or Ultimate or whether it was an Upgrade or Full Install, the CD is exactly the same, as all your really paying for is a CD key...so while it seems rather confusing I think MS have actually done it very well.

This is due to features built into XP Pro

Besides, if you later decide you do want any of those features, Vista has an instant upgrade feature.

What no one seems to comprehend is that the content producers don't care about you. They really don't. They are the ones who want the DRM in place, and those systems that lack it (Linux, for example) Will simply be unable to use any DRM'd content.
What no one seems to comprehend is that you are the consumer that purchases the product from content producers. If you don't stand up for your rights as a consumer, who will? So let's all use systems that allow the DRM to be disabled (Linux, for example) and the content providers will follow... and guess what? They will STILL find a way to make money.
and especially wondering about volume licensing and if that is going to be available for it as well...
Ok... only newbies would upgrade, and newbies don't format. So there are going to be all these newbies with XP that hasn't been formatted since installing (3-5 years?) with loads of junk, upgrading to Vista...
I expect the same thing to happen when XP came out, upgrading will result in a Vista install that crashes and runs like ****, forcing the user to format anyway.
I clean install anyway
Maybe 3 or 4 years when M$ kill support totally for XP Pro
