I'm super hyped for it :)
3 new phones (2 flagships, will be perfect to replace my 1020 at some point), Surface Pro 4, new Band (I have the old one and I love it).
Then, maybe some Hololens news because we (those who are subscribed to the Hololens mailing list) received a mail telling us that they will make some nice announcement so. I would love to get a release date for this baby.
I'm not expecting anything related to Xbox One (even if now Microsoft is really talking about it as a Windows 10 device too)
