Timing of rebrand - should I want for Shopify 2.0?

We are going to undergo a big rebrand - name, design, colours everything. We have the upfront work done and now need to start on the store design itself. But im not sure if its wise to start with one of the templates now…or should I wait for some to come out for Shopify 2.0? I thought they were supposed to come out in August but I have not seen anything. I do not need the final site to be ready until Oct/Nov.

Any advice, or news about timing on the new templates?

There are already various theme that implement Shopify Online Store 2.0
