Portal Has a New Ending

A second update to the three-year-old Portal has changed the ending to the game, throwing fuel on the fire of sequel rumors everywhere.

There was a second update to Valve's beloved Portal earlier today, after the update on Monday that spawned the feverish ARG that seemed to be hinting at a new Portal game - or something like that, anyway.

This update does very little other than changing the very end of the game. I'm not going to spoil it, but let's just say that it makes rumors about an unveiling of Portal 2 at next week's GDC seem significantly more likely.
