Well I was (mildly) interested about whether the free upgrade to 10 is happening after June or not and what happens after. There has been no news and surprising little discussion of which build we will all be on next month.

It is a valid question I think (although I guess no-one knows).
MS did state that 10 would be the last name for Windows and from now on the only change should be in the build/version numbers.
