So I downloaded the new client last night and started up the game. Seems as though they temporarily had the US/Canada servers up, which was shown in Levi's post. Turns out that they were testing the server, so I tried it out.
First off, the new interface looks amazingly better than it did in closed beta.
Second, it looks as though they fixed the lag problem in game. You still get the minor lag 30 seconds into the game, but nothing more afterwards.
Third, they added a new map that wasn't even in Closed Beta that's located at the top of a tall building. I wish I could remember the name.
The weapons they start you off with were the same as in Closed Beta, except they expire in 30 days. So you have a month to earn your gold and get those bad ass weapons you loved in Closed Beta.
