Some good ones up there^.
I think for me, the biggies were:
1. Vettel. He's very good, the team's very good, and the car was designed by (as somebody else said in another thread) a genius, but even so... the extent of the domination was way more than I'd expected.
2. Kimi to Ferrari - WTF? That has got to be the biggest surprise for me.
3. And of course, McLaren.
4. Webber retires to go sportscar racing as a Porsche factory driver. Retires - maybe not so surprising. Sportscars - ok, happens frequently enough. Porsche factory ride - that was a surprise to me, given all the other hot shoes they have available (RIP Sean Edwards however).
I'm sure there are others. Testing controversy doesn't surprise me at all though, seems every season there's some minor scuffle over a team or two bending the rules.
Whimsical #5 - Webber didn't punch anyone (not anyone in particular of course).
