I'm a bit late, but definitely a great poll!
1.Which are the 3 events ( team or individual sports) you are looking forward to watch the most?
Athletics (all events), mountainbiking and track cycling (esp. men's team sprint!)
2.If you were asked to support 3 other nations at the Olympics apart from your own, what would they be?
Italy and France mostly, I guess I'll pick for the third.
3.Who are your 3 favourite all time Olympians?
Dutch: Pieter van den Hoogenband (swimming), Epke Zonderland (gymnastics) and Ireen Wust (speed skating). If non-Olympian athletes also counted, I would've gone with Arjen Robben (cutting inside) as well.
International: Eliud Kipchoge (marathon), Nafissatou Thiam (heptathlon) and Kevin Mayer (decathlon)
