Not so much analysis as an awesome plot idea:
Old Man: Lavos is dead, and I expect the Gates
will soon shut too.
If you don't return to your own eras now, while you
can, you'll become temporal wanderers.

Yes, I'm adding the main ending right now. KWhazit is going to audit the entire script for any last errors or awkward-sounding lines, then he'll translate the Programmer's Ending (which...has a lot of cultural humor in it, so expect it to take a while). Then it is up to me, ZeaLitY, to unleash the passion of youth and prepare the scripts for release.
