Might be missing something here or is this a bug?
Using rc 1 i have created my product type, products and a product display content type. Everything appears ok when i add products (eg i can get the images, prices etc to switch depending on the size / colour selected) what i cant seem to do is make the product sku visible...? I have set to shown on products / manage display, but the option to make sku visible doesnt appear when managing display on my product display content type. Seems to be an oversight as all the other product related fields appear once the node type has a product reference field attached

Can you suggest anything?
