The update will be released this Tuesday, April 29th...(2014).

In all seriousness though, I'm so excited for the new medic achievements. 

Medic is my second most played class, I love it! 

Yea my second most played turned into medic somehow. I hate playing with teams that don't have one or have shitty ones so I just do it to win.
@epsilon I know I'm going to spend some time with this over GTA IV.

I'm guessing 11:55PM ish Pacific time, much like when TF2 beta hit.
Better take a nap and hope its out late tonight.

 I know, right? I'm so excited for this update, but we all know it's not gonna come until the last minute...

Curse you Valve (but keep making excellent games)! 

I have been playing all day in hopes of it hitting at any time ha.

Okay, just loaded up the game and it wasn't much fun tonight.

There weren't many servers up and those that were were almost all medics. Playing on a team with ten other players, eight of which are medics is kinda lame.

Sigh, I'll give it a few days
