I read the news on this blog: http://blog.furuknap.net/sharepoint-2013-name-confirmed-and-sharepoint-store-details
I think it is important to share those information with everyone else.
Also I'm surprised that it's called "SharePoint 2013", I was waiting for "SharePoint 15" oder maybe "14". Second thing is, that there may be an "Office 2013".
So please read the posted link, which might come in handy.
