Google expected to launch wiki and presentation services this week

Several signs are pointing to the imminent launch of Google Wiki and the company's long-awaited presentation service at this week's Office 2.0 conference in San Francisco.

The biggest indicators are history and vague comments by Google officials. Last year's Office 2.0 brought the launch of Google Docs and Spreadsheets, and Jonathan Rochelle, the product manager for Google Spreadsheets, will also be at hand for the opening panel at the conference kickoff on Thursday. Between this, an almost-demo by Google's CEO Eric Schmidt of the presentation application, as well as a post on the Official Google Blog that presentations would be making their way to everyone "this summer," and we should be seeing something new as early as Thursday.

The new wiki application from Google would fill out its online office suite, and give Google Apps a little more appeal for small- and mid-size business customers who want a consolidated wiki solution. The launch would also coincide with the anniversary of Google's acquisition of wiki service JotSpot (review) last October. Considering JotSpot served up multiple tiers of service to serve casual to business users, the model could follow suit with Google's four flavors of Google Apps, including their business and enterprise solutions.

However, the trail of clues about how these services will tie into Google's existing online office environment is thin. There have been few signs of Google's presentation service making an early appearance since the acquisition of Zenter and Tonic Systems a few months ago. From the outside, the clearest indicator has been the move of Jotspot's user help and forums services over to Google's own native support network.

Stay tuned.
