I don't agree with everything you said, but it does seem like it ought to be just an expansion.  But console gamers seem willing to pay out the ass for everything, so it's no surprise devs will take advantage of it.

I wasn't thrilled with L4D but I think I will buy L4D 2 just to boycott the boycott.

Hooray for not actually reading =D

If you don't see value in L4D 2, don't buy it. Since this is mostly discussing the PC game, the mod community will keep you busy, and Valve said in the article I sent that map packs and updates will not be affected.

No reason to throw a tantrum over it. You make your choice, let other people make theirs without seeing some big scare campaign to boycott the new release.

Meh.

1. We don't really know what plans Valve have yet. They're past masters at building and maintaining communities and it may be that the two games are melded together in some way, ensuring that the original game doesn't become obsolete.

2. Even if L4D1 becomes obsolete, I've still had far more hours of enjoyment out of it than just about any other game in the last couple of years. We still might get the extra content anyway, but if not, it was well worth the £27 I paid for it.

Is L4D2 coming to the PS3?

l4d2 will be just as i called it, like a short episode content. i think fans might love this. but its not for me.

no 360/PC only

Uh, since when is a short episode content an etirely new 5 "chapter" campaign?  The only things that are seeing minor changes are the overall graphics.  I'm sure they'll squeeze in some more new weapons, new enemies, and as my article I linked to, this one develops the characters and story behind the L4D world to a much greater degree.

I've watched all the preview game plays thus far, not just a trailer, and the people who made the group have as well, it's L4D 1.2, I can understand the 360 only owners going "woo yiha L4D2 yes booya we are used to being money cows!" But I'm just gonna give the finger and help making a mod on PC. almost 6k now btw -_^.
