For me it's just the not knowing aspect. Will it or won't it happen? Trying not to get excited but still getting excited anyways. Fully realizing that all this could be for nothing. All the forum posts, sharing of memories about the game, talking about builds and power sets and what the first thing you're going to do is when the lights come back on. The fact that all it takes is a "no" from some unseen person and this is all gone, it's hard to handle the feeling of balancing on the edge of a cliff every day.
If the game takes a year before it's back, that's fine. I just want NCSoft to tell us either way so that we can really settle into the excitement, or let it go and focus on one of the new IPs
