It's a major game release by a high-profile developer (Valve), so you should be able to buy it at major retailers that sell computer or console games. You can only purchase it for PC or Xbox 360.
You can also download it through Valve's proprietary download service called "Steam." You will need an active internet connection to download the game. It currently costs $49.99 retail or download.

No, Left 4 Dead 3 is not coming out. There is only Left 4 Dead and Left 4 Dead 2. Both fun games.

No, left 4 dead will only work for left 4 dead mods.
You can't get The Passing on Left 4 Dead 1. It is only a DLC for Left 4 Dead 2.
Not Left 4 Dead 1 or 2, but Valve and Havok announced the Haggard in Left 4 Dead 3.
