Something Smells Fishy (and it's not the Chinese food)

Hm,

A "required" day-one patch for Starcraft 2?  That doesn't really sound good.  Apparently it's for the new Battle.net, not the game itself, but I'm still a little cautious about this.

Now, I haven't had any professional experience in game making, but is it too late to just implement this stuff in the code? Are they that far along already?  They haven't put out a release date yet, so why the patch?  Are they planning on releasing the game sooner than I thought?

Or is this just like the day-one DLC in other games like Mass Effect 2?  I doubt it, but the possibility actually scares me a little.

*Sigh*, I guess I'll just have to wait a little longer and see.
