After Service Pack 1 went live this week, I decided to provision a new Office 365 tenant to see if the OneDrive changes are present there as well. It turns out that they are. When you login, you'll see OneDrive at the top. I really wish this would say OneDrive for Business to avoid confusion with the consumer offering. However, I think this is a screen real estate issue.
Tenant administration has the naming right.
Clicking on the OneDrive link, looks similar to the old SkyDrive Pro experience.
My existing tenants still say SkyDrive. I suspect they will stay that way for quite a while, but maybe we'll hear more at SharePoint Conference. If you happen to hear anything on the timeline of this during a session, please let me know with a comment or tweet!
