Nothing's set in stone until the public preview next month, but it's likely to be: * A start button (not menu) on the desktop mode taskbar, having the same functionality as pressing the Windows key * The option to boot into desktop mode instead of the start screen * More tile sizes (1/4 small thumbnails, and 2x large) for the start screen * 50/50 split view for Win8 Apps in addition to the ~25/75 option * Internet Explorer 11 * A rollup of windows update patches to date They'll probably also announce the 7.5-inch Surface tablets at the same time. They're getting 8.1 to OEMs so the next generation of Win8 tablets can ship with it.
