I don't really understand the ALL CAPS thing, it's not actually that Metro* and I'm not convinced it actually helps in solving the issue that there are so many menus that it looks too busy with normal text. They do seem to have done a much better job with the use of colour though, that's starting to look like a big improvement over VS2010.

 

*Although to be entirely honest, the VS UI is so far away from what Metro is all about that I can't see why pretending to embrace some aspects of it is necessarily a good thing at all.
