Despite not actually featuring it on the show floor, the World War II FPS franchise Call of Duty has been creating some waves at E3, with the news that the next iteration in the series will not be appearing on the PC; and the quiet news that it will be getting a Playstation Portable release.

The news did not surface on the show floor, but in a keynote to Activision investors and an official product release schedule. First up CEO Bobby Kotick told a group of investors that the next Call of Duty will not be featuring on the PC. "[It is] not a PC product, it's a console product and it's all next-gen," he told investors.

Of course Activision may announce a separate title for the PC, as they have done platform-specific iterations of the series, with Call of Duty 2 on the PC and Xbox 360 and Call of Duty: Big Red One on the Playstation 2 at around the same time as one another.

The upcoming console-only iteration will be developed by Treyarch, who did Big Red One whilst the original CoD developers Infinity Ward worked on CoD 2 for the PC. It is not unlikely therefore that Treyarch will produce console specific, and Infinity War PC-specific, versions of CoD in the future.

The Xbox 360 and Playstation 3 are the obvious choices for Call of Duty 3, having the graphical muscle associated with the series. However, a Wii version may also be in the plan, with the Nintendo logo having appeared on some promotional materials. It's not clear, if the Wii version - if it even exists - could be a straight port of the 360/PS3 game, or an entirely separate beast designed with the Wii graphical and control capabilities in mind.

Meanwhile, a version of the game for the Playstation Portable has been quietly announced through an updated release schedule from Activision. No actual date, just the working title of "Call of Duty 3 PSP", with the rumour mill suggesting that it will be an original and separate entity to the console and possible future PC iterations of the series.

It's not clear why Activision hasn't actually been showing or announcing any of this from the high heavens at this years E3, perhaps suggesting that all the games currently on their plate are so early in development that we might not see them anytime soon, but in the time frame of E3 2007.
