If they have made this API they might as well make metro skinnable and for it to be completely customizable. Have all sorts of weird ui elements and not just squares.
How long before we can have the same sort of features that we see in rainmeter application. How long before we have graphs of system usage?
Give it time and all these things will be there...
Don't expect it to happen on pre-beta releases though. I don't know any developers working on Win8 projects yet. They're just tinkering with the new APIs to see what they do and how they work. Nothing serious.
Give it 8 months and it'll be a whole different matter!
