They did? The tweet that announced stuff from the head of marketing did not mention 3 days.
That said, I believe you. Some press gets a hands-on on Wednesday (today) so unless they plan to pre-announce something (unlikely) or announce software only stuff, I think today is it.
"This is a huge week for the Mac, and this morning, we begin a series of three exciting new product announcements that will take place over the coming days," said Apple's hardware engineering chief John Ternus, in a video announcing the new iMac.
That's disappointing. I was expecting a new Apple TV because mine needs replacement and I don't really feel inclined to get one that's due for an upgrade very soon.
The current-gen Apple TV is already overpowered for what it does, and extremely nice to use. I can think of very few changes I would like to see, and most of them are purely software.
It would make more sense to discontinue the smaller model along with some other updates to the line. Or in other words, Air won't receive any other updates this week unfortunately.
