Brian Madden summarized what looks like the future roadmap for Citrix based on one of the sessions at iForum in Scotland - "Citrix Presentation Server Futures".  Looks like Ardence integration might have to wait until 2009!  Brian writes:

One of the last sessions from iForum in Scotland last week was “Citrix Presentation Server Futures.” This article is a summary of what’s coming in the next few years.

Please remember of course this is all subject to change and this is only what they’re talking about publicly. Who knows what the future will really hold?

In general, Citrix is hoping to create what they’re calling a “local experience or better” with Presentation Server. They mentioned a few IT trends that they’ll be paying attention to:

• IT professionals are more and more becoming “generalists,” so it’s important that the products that Citrix makes are easier to architect and use.
• A “hypervisor pervasiveness” will continue to affect all aspects of computing, from the server to the end device.

The very short version of these next three years looks like this:

• 2007: Presentation Server “Ohio” (released this past March as v4.5)
• 2008: Presentation Server “Deleware” (mainly a code update to work on Windows Server 2008)
• 2009: Presentation Server “Parra” (lots of new features and the next major PS release)
