Well, I'm alright with seeing Namorita or Microbe (I think that's his name) die, as I'm not very attatched to either of them, but I'll be sad if Speedball or Night Thrasher die. I'm hoping Speedball's the survivor myself, but we'll see. Of the four, he has the most potential to move on and be something bigger than a C list character.
And District X was one of the best books out when it was canceled. Bishop's moved passed that whole from the future thing, so he's fine where he is. I like him a lot, but I would like to see him and some other X-Characters spread themselves out beyond the X-World.
