Design Guidelines for Windows 8 Metro apps

Question I start to hear often: where to find good online resource for Metro UX design guidelines ?

1. Well, when first going to MSDN you’ll find this page “Designing Metro style apps” which I find a bit harsh (hello pictures?):
http://msdn.microsoft.com/en-us/library/windows/apps/hh465427

2. Far better is the “UX guidelines for Metro style app development” article on the Blend Insider blog, which in fact is a well organized list of MSDN links grouped by topics:

3. And then, this awesome “Windows 8 Touch Guidance” document by Microsoft:
