Gates helps Microsoft flex video-game muscle

Seattle PI | at | by Mike

Microsoft sought to strengthen its video-game muscle Tuesday, announcing a new installment in the lucrative "Halo" series, a deal with an industry powerhouse, an updated forecast for Xbox 360 sales and a plan to connect its game-console and PC Windows businesses.

The company even brought out Bill Gates to take part.

As part of the appearance -- his first ever at the E3 video-game show -- Gates introduced an initiative called "Live Anywhere" that will expand the Xbox Live online system to mobile phones and the next Windows operating system. It means, among other things, that Xbox 360 gamers will be able to play online against people using Windows PCs.
