The thought a few weeks ago that all Windows Vista versions were going to ship on the same CD has been said to be incorrect by Jim Allchin, Co-president of Microsoft’s Platform Products & Services Division. He pretty much said that there isn’t enough time to gather everything needed and compile it all to the same CD. I am sure the hardest portion would be the security of each different version, because you wouldn’t want someone paying $100 to get a $300 version that easily.
They will, however, offer a ‘Windows Anytime Upgrade‘ plan which allows users to upgrade their version of Windows without any hassle. Details on how it will work have not been released, but I am sure they are just working on getting Vista done and more CTPs released to the public for testing.
