L4D DLC in September

Valve is releasing a DLC pack next month for L4D that includes new campaign content, as well as a new "Crash" multi-player mode. Though it will be free on the PC, it will be 560 points on Xbox Live (around $7 US). With H3: ODST dropping on September 22 and L4D2 coming out in November, I don't see any reason why somebody would go and buy this, but interesting tidbit nonetheless.

Thx OmniscientDeath for the tip.
