I admit I was a bit surprised when Valve announced their appearance at QuakeCon 2007 last week to show off the new game they helped develop, entitled Left 4 Dead.

We’re headed to QuakeCon 2007 next week. If you’re one of the 7,000+ lucky attendees, be sure to stop by booth 221 to say hi and play a few rounds of Left 4 Dead. Valve and the Turtle Rock Studios design team will be on hand to answer questions about the game. We’re giving away some cool schwag, too. Next week, we’ll fill you in our visit to the show.

Understandably, QuakeCon has become more of a trade show than just a LAN party, especially with the trimmed-down version of E3 we have to put up with these days. But could it be indicative of a future partnership between the Doom Guy and the One Free Man? This site speculates as much, but we won’t know for sure for a few more days, at least until id gets a bit more talkative about their next gaming engine, “id Tech 5.”

Update: Looks like we called it! Strange that it happened the very same day O_o
