Legend of Korra--My Fan Theories

I've only seen the first couple episodes of the new Avatar series, but I've got a few hypotheses I want a record of so I can say "I told you so" if I'm right. Since this is wild guessing on my part, I had a little fun with the more "out there" theories.

1. Amon is the son of Sokka and Suki. Sokka subconsciously passed down his inferiority complex about his inability to bend and Suki's Kyoshi Warrior face paint taught Amon to protect his face. Alternatively, Amon is (or is descended from) one of Aang's non-bending children.
2. Tenzin is the reincarnation of Pakku--both are traditionalist masters of the Avatar who can be grumpy when they don't get their way. Alternatively, Tenzin is the reincarnation of Gyatso and Momo.
3. Lin Bei Fong did not have a good relationship with the Aang when he was alive--and he may have been responsible for the scars on her face. Aang wanted Tenzin to not pursue a relationship with her due to the fear of other-bender blood diluting the airbender line. Lin also killed Avatar Aang when he was only 68 years old.
4. The guy in the bushes will be either important to the plot or recurring like the Cabbage Merchant. He is also the son of Doc/Shu/Bushi.
5. Dante Basco will play someone who works at the local Jasmine Dragon outlet, who happens to be descended from the girl Zuko went on a date with. His name will be Li.
6. One of Tenzin's kids will try to become a pro-bender with little success. It'll most likely be Child #2.
7. A descendent of The Boulder, known as The Pebble, will be a pro-bender...and possibly the old guy who tried to throw Korra out of the arena building.
8. The hippie nomads are still around. They've discovered onion and banana juice--and maybe chakra sandwiches.
9. Aang will look like a young-ish man when he spirit-visits Korra. He will also have a beard and chained up pants.
10. Mako and Korra will fulfill some of the desires of Zutara fans, but not all. It'll take the pair a while (and at least one super-awkward date between Bolin and Korra) before "Korko" becomes official--at the season's end or worse.
11. The Lion Turtle will return and teach Korra how to give people bending. She will not use this power, however, until Tenzin and his kids are in danger of becoming the for-reals last airbenders.
12. There will be four episodes total in which pro-bending is the A-plot. Losing the championship means defeating Amon forever.
