Spencer: We Have Just Signed Exclusives That Won’t Be Ready for 2-3 Years, No Point in Showing Them

[Kaneman!]

So much Xbox hate on these forums, it's impressive! MS must be doing something right.

On topic, Spencer is right. a reveal has more oomph if it's announced for the upcoming year, not many years in advance. You wouldn't see Bethesda announce TES VI 2 years in advance either.
