HBO and GRRM basically made it clear in Season 1 with the beheading of Ned Stark, who seemed to be the "main character" of the show, that nobody is safe from the wrath of George. It even seemed unlikely that Robb Stark would be dead after just three seasons. However, it's still hard to see certain characters being killed off.

Which characters do you think are "safe" from death, at least for the next few seasons? (Let's say season 5, which is probably around the end of what's been published/the fifth book.)

For me, I have to go with Jon Snow, Arya, Tyrion, and Dany. I just can't see these characters that have huge storylines and tons of airtime centered on them being killed off. When Ned was killed, it at least opened the door for other characters to take the spotlight, but I'm not sure that can happen with these characters. Though I'm sure I'm in for quite the surprise.

Everyone else, they're all fair game as far as I'm concerned. Feel free to mention which characters you think are sure to get the ax in the next few seasons as well.

EDIT: oops, forgot to mention that the questions are mostly for TV watchers only. I'm looking for predictions of people that have seen only the first three seasons and haven't read anything that hasn't been in the show, though book readers feel free to comment otherwise.
