This is an opinion thread (and expectation is a subjective thing, since that's a term related to personal thoughts and feelings). It's about things you expected, and something else happened. Which ones subverted your expectations the most?
Me, it was GTA IV being outsold. I didn't expect it to be the Wii killer the HD fanboys were praying for, but I didn't expect Wii Fiit and Mario Kart Wii to outsell both versions combined.
(EDIT: Or maybe I did with MK Wii, and forgot about it, but when I saw it, I was a bit surprised)
Also, FFXIII on 360. I wasn't surprised, but I didn't expect it, at least not as a semi-simultaneous release.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
