Microsoft says it will finally give developers a peek at the next version of its omnipresent Windows operating system, code-named "Longhorn," in October at its professional developer's conference in Los Angeles. However, conference attendees should not expect to get their hands on a full beta version at that show, as the folks in Redmond are promising only a "developers preview."

Still, Microsoft execs insist that they will come through with more than just slideware. In fact, the company is expected to distribute hunks of Longhorn's source code and to provide attendees with a real taste of the look and feel of the new OS. They also plan to hand out SDKs and tools that support Longhorn's new "managed APIs."
