those camden's just won't go away

so 7th heaven was over. series finale and everything. i was not in the least bit broken up about this. it's about time was more like my reaction. but then the other day i find out that the new cw network has renewed the show, and is bringing it back. is that even possible? i mean the story was wrapped up, over. how does 7th heaven stay on, but w&g is over. it's just not right.
