I feel like the matchmaking changes will come pretty soon, because they only have to work on 1 thing rather than working on 3-4 things. I expect it'll come with smissmas. Jill implied that it was ready, but wasn't worthy enough to be a refresh of the mode. So I expect that there will be some major changes to matchmaking, other than the ELO or placement matches.

This summarizes it up pretty well

I know it's /r/tf2 but this is actually a decent post with all the info from the different days.

I wonder what's gonna happen with the newbie mixes. Will we be allowed to mess around with playing the pyro in 6s?

you know I'm gonna put that Freedom Wrapped skin on the rocket launcher

definition of imminent is "about to happen"
valve said "we promise" in the blog post too
it'll probably be either next week or the week after that

It added the legit implementation of the Steam Datagram system into TF2

Here are the words from Valve on what it does:

Instead of communicating directly with the gameserver, your client will select a relay and communicate through that relay. There are a few advantages of this method. First, this will eventually allow us to remove gameservers from the Internet completely, which greatly protects them against all sorts of attacks. Second, if a DoS attack prevents you from communicating with a particular relay, the client will automatically switch to different one within a few seconds. And finally, having different relays to choose from means the system can select the route which actually results in the best connection to the gameserver. For example, this relay protocol has been in use on Dota for about a year now, and the majority of Dota players playing in the US are experiencing a modest ping improvement compared to the route direct to the gameserver that they would have gotten with standard IP routing, because their client is selecting a relay closer to them. This also means that their traffic spends more time on Valve private dedicated links compared to the general Internet.

In CS:GO it also has a cool feature. When you go to "Game Info" when you right click on a friend playing CS:GO, it'll show something like "Competitive Inferno 5-2" rather than showing you the IP address and number of players etc

he's not

EA ported the Orange Box to the PS3

The new voice codec is the default for all servers now.

It sounds better with human voices than with music.

this proves that delfy doesn't do anything but cause bad things for tf2

According to the Google Chrome extension Ghostery, TFTV uses Google Analytics and "sovrn" (formerly known as Lijit Networks)

these are the kind of updates we need more in our lives

It's the Pomson 6000, not the 5000.
