1) A new version of Office Communications Server (likely to be called Microsoft Communications Server 2010).  Here are the highlights:

• A full software powered communications stack, including capabilities intended to make a PBX unnecessary.
• Enhancements to the resiliency and reliability capabilities of OCS 2007 R2.
  • More branch office survivability options.
  • There will likely be re-routing capabilities depending on the network or PSTN outage.
  
• Remote Call Control (RCC) will still be supported in Wave 14, though the future beyond that is uncertain and Microsoft generally recommends other integration options.
• Location Awareness:
  • The ability to provide location information via a new server role: the Integrated Location Information Server (ILS).
  • Location information can be sent on the SIP channel and used in the E.911 scenario.
  • Location information will be integrated into the next release (W14) version of Communicator.
  
• Call Admission Control:
  • The ability to use bandwidth information and policies to allow or disallow if a video call can be initiated.
  

2) A new version Office Communicator (code-named “14” right-now).

• Will likely be called Office Communicator 2010.
• The Communicator Tabs extensions will likely be deprecated.
• SharePoint Integration:
  • New Communicator “skill search” functionality built into the next release of Communicator that searches SharePoint profiles to find people with the skills you are looking for.
  • Initiate audio and video communication directly from SharePoint search results.
  • Phonetic based search in Communicator to locate associated SharePoint information.
  
• Voicemail Features:
  • Visual voicemail capabilities directly integrated into Communicator 14.
  • Multi-language translation capabilities (with Exchange 2010 voicemail integration).
  • Ability to jump to a specific point in voicemail.
  
• Test Calls: the abilility to place a test call directly from the Communicator client will likely be added.
• Music On Hold (MoH): this functionality will likely move to the client.


3) New OCS Server and Client Development SDK’s:

• A set of fully supported (not just samples) Communicator controls in WPF and Silverlight.
• UCMA 3.0 will be a server-side API with workflow activities.
• An Early Adopter Program is available if you are interested in getting an early look at the SDKs
