A 9to5mac reader writes in telling us he/she’s found some interesting files in Lion.  These files are labeled “MobileDocumentsFolder.icns, Mobile Documents 32.png and SidebarMobileDocumentsFolder.icns” and show new types of icons for a Cloud file system.  Clearly, this would seem to be the successor to iDisk and is probably shows a more transparent interface between the desktop and the Cloud, perhaps a little more like Dropbox. We’re also thinking there is an iWork.com component as well since these are “documentsFolders”.

– here’s the new sidebar icon.

We’re expecting to hear more about the future of MobileMe at the iPad 2 announcement next week.  Hope this tides you over until then.
