Jason Calacanis’ Weblogs Inc has announced the publication of an insightful interview between Engadget Editor Peter Rojas and Microsoft Founder Bill Gates.

In part one of a two part interview series published today, Peter Rojas spoke one-on-one with Bill Gates about: the launch of the next Xbox console, Media Center PC, whether or not Microsoft is going to come out with a competitor for the PlayStation Portable, Microsoft’s mobile strategy, and the future of Windows Mobile.

The second part of the interview to be published tomorrow includes HD-DVD vs. Blu-ray, IPTV, Windows Media Center, and why Tablet PC has struggled so much.

The scoop in landing Gates for Engadget in both a bonus for the network, and further signs of the maturity of blogs as major players in the news and media field.
