Forbes has an article on the release of Doom 3 where an analyst says that the game might just be what PC gaming needs to get a boost again.

Analyst Michael Goodman with the Yankee Group said “Doom 3″ could boost the sagging market for personal computer games. Sales of CD-ROM-based PC games dropped from $1.4 billion two years ago to an estimated $1 billion this year, largely due to the growing popularity of consoles like the Xbox and PlayStation 2, he said.
