I can't wait to watch the whole season of this show on TV with everyone else (instead of watching online a couple hours later - I got HBO just in time for last season's finale) and discuss the plot points.
I don't know about John Snow. I'm assuming he's dead but I'd rather wait for the actual show to see what happens with that.
I did see some photos from the upcoming season. Don't worry, I won't discuss them here. I also don't want to try to analyze them for what they might mean. Again, I'll wait until the new season.
