Bink is reporting that there are two releases for Sofgrid on the way. SoftGrid 4.1 will be upgraded by Service Pack 1. This will include Hotfix and critical updates and increase stability and compatibility. MS will release the Sequencer, Desktop, Client, Terminal Server Client and Server all at the same time in around April or May.
SoftGrid 4.2 will be a desktop only release, i.e. not for Terminal Server. It will include Vista support for the sequencer and the client. Expect to see a release around July.
