Next Team Fortress 2 Update To Get Friendly?

Watch this video. Listen to the lengthy looping of audio files reportedly dug up from the depths of TF2's latest update, dated December 7. Then try and make heads or tails of what it all means.

It seems to be suggesting that a new game mode is on the way for Team Fortress 2, one that sees players from opposing teams joining forces, much to the displeasure of the announcer.

So, what, you start a normal game then the teams are randomised? Reds and Blues vs Blues and Reds? That's one of my two impressions, and it's an intriguing one.

My other impression is that this is Valve, and this is Team Fortress 2, and both of them take great delight in fucking with us, so who knows, it could be the reddest of red herrings.
