This Activision press release announces a new line-up of PC and (mostly) console games based on the popular Marvel comics in the Spider-Man and X-Men series (thanks AVault). While details about the games and their developers are scarce, one of the titles will be a Spider-Man game for the PC, as described in this excerpt:

For the first time ever, computer gamers can live the fantasy of Spider- Man in 3D with Spider-Man for the PC. Players can leap, crawl and swing anywhere in free-roaming, 3D environments while exploring both the tops of skyscrapers and the underbelly of Manhattan. In order to bring justice to a crime-ridden city, players must face off against Spidey's legendary gallery of super villains with a variety of attack combinations and a vast arsenal of webbing including impact, trapping, web spikes and the web dome. The game also features cameo appearances by some of Spidey's greatest allies. Spider-Man for the PC is scheduled for release this fall.

Update: this GameSpot story clarifies that this PC game will be a port of the Playstation game released last September by Livesay Technologies.
