An important personal note to the FG guys

[Fred]

You can expect a great amount of the Left 4 Dead players to move on to Left 4 Dead 2. Not only that, Left 4 Dead will not receive much new players, because there is Left 4 Dead 2.

So even if they will release content, it wouldn't be really useful. That is why I dislike it, they should have just focused a 100% on Left 4 Dead and release Left 4 Dead 2 in 4 - 5 years when possibly the whole Source engine gets a big nice graphics update for the next Half-Life game after Episode 3.
