New Left 4 Dead Campaign in September

Valve has announced through their online distrubution system Steam that the original Left 4 Dead will be receiving a new campaign titled "Crash Course" this September. Unfortunately they will not be able to keep their "DLC for free" mantra going, and it will be priced at 560 MSP (or as they refer to them "Gamer points"). This will either bring the game to the forefront of everyone's mind before the sequel drops in November, or annoy people to the point of taking L4D2 off their radar, as many people have already done due to Valve's "rush" in getting a full retail title on shelves instead of simply releasing extras through DLC.

But, before everyone goes all anti-Valve... the price of this DLC was not their decision. Microsoft is undoubtedly forcing it on them. I'm sure they won't refuse the paycheck from any downloads, but they'd still prefer any post-release content to be free. Time will tell if they throw in some extra achievements for the trouble, but if they had the content ready to release for free on the PC, they may as well offer it to the 360 users as well, even if they can't just give it away.
