There was a major announcement today for Office 365 customers. Microsoft has now publishing the Office 365 roadmap publically here - http://office.microsoft.com/en-us/products/office-365-roadmap-FX104343353.aspx. This is huge and been long awaited. This solution will allow enterprise customers to review the roadmap and prepare for change. I say this make the Office 365 cloud “predictable”!!!
Additionally here is an announcement about the new Roadmap site and the First Release program - http://blogs.office.com/2014/06/19/improving-visibility-to-service-updates/?wt_mc_id=publicroadmapsocial. The First Release program was announced at the SharePoint Conference and it is a new solution that allows customers to opt into a program so they can receive new features and capabilities quicker. You do not have the option to select on a feature-by-feature basis; you are either in the program or are not.
