As long as you don't consider random snippets of the game's environments and cutscenes, 2/3rds of a dungeon, a full boss fight, and one other random section from the game (fishing, stealth, exploration/enemy camp) to be spoilers, you'll be fine.
Add treehouse on top of that, and I expect the full intro to be spoiled as well.
Pre-e3 blackout for me. Nothing from here to launch, if I can help it. I know I won't be able to avoid the title, the amiibo (and therefore characters), and some random screenshots/gifs, but I should be able to avoid quite a bit.
Plan is: No gaf/twitter for 2 weeks starting on Nintendo E3 day, mute aaaaaaaaany zelda related terms I can think of, stay off major video game websites, unsub from gamexplain/other media on youtube who would cover zelda on a weekly basis, and obviously don't click on any zelda related gaf threads.
The less I know the better, but I know I can't avoid it all without quitting the internet for 9~ months (or at least my favorite parts of the internet)
