Ready to launch in approximately: 2 days

Yes, that’s what steam tells me. 2 days 9 hours, to be a bit more precise.

While I appreciate when a game gets improved and bugs get fixed, having a multi-GB patch right after launch is damn annoying to those who live in an area with less-than-perfect net connections.
What sort of change does require this much changes? code fixes and text will be kB, MB at most; some voice acting or map patches MB but not a GB. Do we get a full set of graphics now? What’s in the damn patch?
