Due to a lot of comments about how much ABC loves the show, the fact that they've gotten solid ratings with only reruns for a lead-in (other than the Sunday airing, which had its best ratings), I'm pretty confident it will be back next season. (Unless it does badly tonight, but I don't think it will.)
Also, I was quite pleased that my comcast DVR had the description of the episode beginning with "the First season finale ..." Sounds good to me.
( So thoughts behind the cut (including a quick rundown on the last episode) )
