If you take a look at Microsoft's new Dynamics site (www.microsoft.com/dynamics/), there is a new logo for the brand. It looks like 3 sails. So Great Plains has moved from from the little prarie logo, to the offsetting color spinning thing to 3 sails. I have to say, I like the new look overall. It's sort of a clean differentiation. Microsoft but not.
Update: I've also noticed that from the website, Microsoft Dynamics is FORMERLY Microsoft Business Solutions. So MBS is truly dead. This is something I speculted about with the branding at the SQL 2005 launch event. This will at least reduce the mouthfull that was MBS.
