You forget a OP doesn't have to have anything to do with the series at all.
[s]Just look at the OP for madoka magica[/s]
Shaft openings are [S]WTF[/S] unique and rarely follow the
generic opening style. Feel free to check some in the spoiler tag.

*Insert Bake/Nise OP's*

Anyways, I'd honestly say Korra would fall under a 'shounen' if ever categorized, and openings tend to stick to to thier genre. Battle shounen anime (well more like action shounen, including sports) OP's are usually something along the lines of:
1. Show main/side/important characters
2. Show enemies
3. Some sort of battle scenes.
4. Foreshadowing, extras, etc.
General battle shounen op examples
