The pre-RTM build of Windows RT is pretty old according to the build string. The build was compiled on the 11th June 2012, almost a month ago. The screenshot reveals two new Office 2013 icons, that being PowerPoint and Word. OneNote and Excel icons have already been leaked in other images.
The screenshot also appears to be running the new "metro desktop" interface, instead of Aero. This means Microsoft have been tweaking and testing the new Metro desktop theme for a little while, it seems Microsoft want to get this right first time.
