What's the point of a so called 'power crown' when your mainstream SKU (probably selling 70-80% of units). Is a 4TF system which devs will need to target. Not to mention the cross-gen commitment for at least a year or two. Hobbled by their outdated CPU and HDD.
Having a high spec baseline SKU, whether it be 10TF, 11TF, 12TF. That's what will allow devs to make these machines sing. And by the time they really get on top of things. We'll be into the mid-gen upgrade cycle.
Without a disc drive I'm not sure if it'll sell 70-80% of their total volume. Also If it comes out later then to be honest I don't think it'll do as well as some people think.
