How does reviews work into these? Is that a separate schema/call? What about coupons/offers? I also like how Semantics has a "features" object (a link to their schema: http://bluetide.pro/gVDk/5qEj1aBD). Can we have something like that? You may need to account for some form of "variation_id" so we can say "iPod", then have variations of like 1st gen, 2nd gen, etc. Or will those just be separate products? Can we get a "images_total" above images that is just a count of that object. Thoughts?

For the iPod example, those would be separate products (sku). This should hold true for items of different color as well, until we get to clothing. I added in the features object (but left it very wild-west for now).
