People have the right to be upset over a 2nd game coming out 1 year after the original, Jesus its not like Valve is making millions if not billions or anything. The reasonable thing to do is give a small discount ($10-20) off to previous owners of L4D. I personally will be buying it no matter what happens, but I still think 1 year is much too early to be releasing a 2nd game and expect full game price once again. The real problem that worries me with this is other company's might see this as an opportunity to spit out more stuffty squeals into the market 1 year after there originals.
