Well, my knowledge is limited to what I picked up in-game and what it says on the Wiki, so I don't know the details. My brother gave me the progress report and I didn't fact-check it at the time - it might have been wishful thinking, though.

Did you know that Kim Swift left Valve? I didn't and just read about it when catching up on Portal 2 news the other day. It's a loss for Valve. :(
