AppleTV was also pre-announced, as was the MacBook Air (available two weeks after announcement).
I sincerely hope the new iPhone ISN'T available on June 9th; I'll be at WWDC, and if I have to run out and check it out, I'll miss a bunch of sessions and events. The top members of the Mac community will all be crammed into a convention center - do you think they'd spend the days reviewing and taking apart the new iPhone, or attending WWDC? Apple has already had problems releasing products immediately before a crowd of that sort, and this year's attendance numbers look insane.
