Hi,
Unfortunately WooCommerce product pages with variations are not production ready yet after installing v2.0.2 as the selected image swatch is changing to all the same. I was hoping this would be fixed as well 
as it holds back a large WooCommerce project i am working on now.
The issue was written here (2nd issue) and added to the bug tracker:
Here i have a V2.0.2 example of the image swatches:
- click on an image variation
- select another image variation
Result: now all images are going into the same.
What to do? Should i submit a new issue into the forum with v2.0.2 labeled? Or could you write it down with an extra â!â 
Thanks!
Joep
