Windows 10 will be a free upgrade for most editions of Windows 7, 8 and 8.1, but not for Enterprise customers. This doesn't really surprise me given the fact that enterprise editions are a volume licensing option to larger companies and are sold at a much lower per-unit cost than other editions of Windows. I don't see it as Microsoft trying to milk the cash-cow; after all offering a free upgrade from their "legacy products" is an unprecedented step.
I think Microsoft is keen to avoid the mistakes they made with Windows XP. When XP was released it didn't really support USB devices, it didn't support a lot of other hardware that has changed since 2001, and nor did it support x64 architecture. In fact, Windows XP Professional x64 was released 4 and a half years after the original in 2005.
Windows XP was very widely criticised on release, with most people claiming that Windows 2k was better. XP though was very very successful in what it was designed to do: bring consumer and business customers onto the same platform. Extended support for Windows 2k ended in 2010, whereas XP ended in 2014 since it was pushed out further by Microsoft since a large consumer base were still using it. And the truth is that Windows Vista wasn't really a great update to XP - in fact many older systems would run slower on Vista than XP. Not so much the case with Windows 7 which was in most respects a huge improvement over both Vista and XP.
So Microsoft should be, as I mentioned, keen to avoid this issue with Windows 7. If Windows 10 is an actual improvement for people running Windows 7, 8 and 8.1 then it will mean they can end support for those products sooner, and I imagine the cost savings will more than make-up for the loss of sales given that consumers rarely choose to purchase a new OS to upgrade their older systems.

"That's disgusting. There were clean athletes out there that have had their whole careers ruined by people like Lance Armstrong who just bended thoughts to fit their circumstances. He didn't look up cheating because he wanted to stop, he wanted to justify what he was doing and to keep that continuing on." - Nicole Cooke
