It appears Canon has solved the banding issue? 6D!

That's not really how the economics works. Someone has to make a profit from every sensor. Canon's sensor business has to contribute its share of profit in return for the capital investment and R&D costs. So, that cost has to be passed onto the customer. Canon cannot pretend that it never made the investment and they get the sensors for just the material and labour cost, so the question is not how much profit is made, but where it goes. In Nikon's case, they may not gain that part of the profit within their company, but then they didn't put up the capital investment or the R&D costs, so that is fine within their business model. In addition it is very likely that the actual unit costs on the Sony sensors is lower, possibly a lot lower then is Canon's. Sony has the advantage of volume, the ability to amortise the R&D costs (such as the development of the Exmor column ADC) over many more sensors and also the advantage of using 300mm wafers rather than 200mm ones.
