First...kudos to valve for releasing free content/updates to keep people interested/invite new people to a two year old game. The spy bug(s) are pretty glaring, and how they failed to catch those in QA testing is beyond me, but I've just disabled spies on all my servers until they issue a patch to fix it.
On the subject of the new "Dual Payload" (or whatever it's going to be called)...my thoughts (which are purely speculation) are that they were going to release it as the last "reveal'...but discovered some kind of bug/errors in the map at the last minute, and they couldn't hit the deadline in time. With midnight approaching on the east coast, they decided to scrub it from the update, and threw that shabby "vote results" as the "Release Day" news, instead of a 6th "feature". If I had to guess, I would think we'll be seeing that map very soon.
I suppose I could bitch about the community map releases (honestly, with stuff like cashworks out there, it's a wonder that they chose those maps), or the lack of a "Meet the" video, but then again....I'm looking at 8 full servers, and people are once again excited about TF2....so I think I'll cut them some slack.
