I've read that Windows 7 will be released with the same editions as Windows Vista except that "Windows 7 Business" will actually be Windows 7 Professional.
Here is the list of editions according to this article
Windows 7 Starter
Windows 7 Home Basic
- X86 only
- No Aero Glass theme
- Limited to only run 3 simultaneous apps at any time.
- As of now, seems will only be available pre-installed.
Windows 7 Home Premium
Windows 7 Professional
- Appears not to be available in the US.
- Also said to only be available pre-installed.
(business edition when compared to Vista)
Windows 7 Enterprise
Windows 7 Ultimate
- Same idea as Vista Ultimate except some features are not included.
- Said to only be available at retail during promotional periods.
See the linked article for explanation/comparison of editions.
I'm assuming there is a good chance this will change considering Windows 7 is not released yet.
