Is he dead or alive? I say alive.....maybe
Like others have said, I believe he is dead but is brought back by the Red Witch. At some point I think he, Tyrion Lannister, and Daenerys Targaryen become the 3 dragon riders and ultimately destroy the White Walkers. Here's why: (pure speculation on my part)
1. Only Targaryens can ride dragons.
2. Jon Snow is the son of Rhaegar Targaryen and Lyanna Stark. This is why Ned Stark never told him who his mother was.
3. Tyrion Lannister is actually the son of the Mad King, the result of the Mad King raping his mother.
Couldn't Bran use his uber-warg ability to get in the head of a dragon?
Interesting idea...never would have thought about it if you hadn't said something. Don't know at this point.
Not only has he been filmed, but he's been filmed not wearing the black of the Night's Watch, but an outfit more similar to what Rob wore. My guess is that Melisandre brings him back to life (basically the entire reason Baric Dondarrion is ever shown and killed - his resurrection is sort of like Chekhov's gun, to be later used on a character that actually matters.
When he comes back, his "watch has ended" because he died, and that loophole allows him to go back to being a Snow at the very least. Perhaps he wants to head to Winterfell to try to rescue Sansa, and runs into she andTheonReekTheon fleeing.
Also, I'm a bit worried that focusing on Euron and the Iron Isles this season is going to be as much of a drag as Dorn was last season. The sand snakes were poorly fleshed out and a bit confusing in the books, and doubly so on screen.
Were he and Sansa not killed by jumping off the castle black? I thought it hsowed them landing on stone? Did they land in a snow drift or something?
2. Jon Snow is the son of Rhaegar Targaryen and Lyanna Stark. This is why Ned Stark never told him who his mother was.

Meera Reed may very well be his twin sister as well. Notice how much she looks like him in the show.
