Some fab looking new features there in the IDE.
Only worrying thing I noticed is the disappearance of the "Solution Platforms" toolbar combo selector. Not just from the default toolbar selection, but it's also absent from the available buttons list shown at 13:54. It might not seem useful to the C# guys, but it's necessary for anyone doing multi platform C++ work. Hopefully it will find its way back in the UI before CTP, or you will have some annoyed C++ developers if there's no way to change the current platform selection.
