Gravity Falls is ended and Bill is dead.

I don't know how anyone even spelled out what he was saying and wrote it down, or else figured it was a backwards message and decided to try playing it backwards, but I think it was making fun of how people always speculate the villain will return even after they're dead (like King Sombra in My Little Pony based on one shot of his horn). Plus, it could be his powers didn't work while he was being erased, or else Stan killed him before he could finish.

But even so, a return would be kinda hard when there will be no more Gravity Falls, and nothing during the shot of stone Bill or otherwise suggested that he's still alive
