Team Fortress Updates

Up until June, there were no major content updates for Team Fortress this year, which shouldn't be surprising for a 5 year old game, but then again, this is Valve, which had released 20 major updates before that (and 318 patches up til now). So I was kind of wondering what was up, until now, when I have been hit by 3 major updates pretty much one after the other.

While I am enjoying all the new content (new items and a new game mode), I am a bit overwhelmed, as I haven't been able to keep up with all the new items, and Mann Up tickets have been eating into my resources, more than any previous game mode.
