So you may have heard about OSLO. If not, you can read more about it here http://www.microsoft.com/soa/products/oslo.aspx
Since its announcement at the SOA conference October 2007, the rumor was that it wouldn’t be available for a couple few years. As such, expected needs for a service pack, updates to play well with Visual Studio 2008, SQL Server 2008, etc suggested an interim release might be needed. As suspected, R3 was announced.
BizTalk Server 2006 R3 will provide us with a number of updates. Since this is not considered a major release, it has taken on the name of R3 to follow the current release version named R2. It is expected to provide operability for Windows 2008, SQL Server 2008, Visual Studio 2008 and.NET 3.5 further promoting next-generation web and service oriented applications, virtualization, scalability and office interoperability.
Additionally, the long awaited UDDI Version 3.0 support for web service registry functionality, new adapters for LOB application, enhancements to industry protocols and additional patterns and best practices can all be expected.
We should see a CTP release sometime during the summer of 2008 with an RTM sometime in H1 2009.
