Again, just because MS says they plan to RTM in june doesn't mean they'll make that date... they may slip it a week or two.
Who wants to make a bet? Gabe Aul tweets at least once with words "Sorry, RTM will be delayed".
Yep M$ is not known for releasing things on time written in stone.
As with most Windows releases, marketing dictates release - be that as it may, I'm sure they will release an adequate OS come the June holidays - or whenever the marketing guys have decided it's opportune - whatever minor bugs have been identified will be passed to an SP branch post feature complete anyway.
