Valve leaving L4D for Dead?

My initial impression when I read about Valve's sequel to Left 4 Dead was, "Didn't I just pay $50 for the first one?" I felt oddly ignored and put aside, as though I had put money into something I felt would be amazing, only to find out the company who sold it to me wasn't into the idea of backing me up. In fact, when I had pre-ordered the first title, Valve apparently had already started development on the second one. But I read the feature list and started to feel maybe I was over-reacting. Until recently.

A group is growing in the steam community called the L4D2 Boycott. While many of its outlined complaints seem somewhat frivolous, the main point is that the sequel feels a bit too much like what Valve promised L4D would become after DLC improvements came along, and that the sequel will only hurt the people who paid full price for the original. This is where I start to feel the argument is incredibly valid.

I have struggled a bit through the last 6 months as to whether Left 4 Dead was worth my $50. The features were cool, but there were a few things lacking that bothered me. The only thing that kept me hopeful was that DLC would likely fix these issues and keep me happy about my purchase, much as Team Fortress 2 has done, and is still doing.

So, here's to hoping this pans out in favor of the current Left 4 Dead players, and that the sequel, if it does come out as a full-fledged sequel, ends up surprising us all and delivers nicely.
