Max is probably right; random unverified information is just that. But it doesn't seem impossible at all that Columbia admitted a few people way early in the process. Every year there have to be a few clear superstars, who every school knows will get admitted by every school, and maybe Columbia sends an early admit to them so they can have time to make the sell against Harvard or whatever. If I were Columbia, I'd do that. Med schools and Law schools operate the same way, although they also compete by throwing money at people.
I don't know about you guys, but the time in between due dates and having to make a decision has so far been just awesome. I have abundant free time and, for the first time since I was a child, no outstanding obligations or projects. Between now and grad school I'm going to live it up. I hope you all do too!
