From why we know about broadwell-e it will consist of four sku's
•Intel Core i7-6950X: 10 cores, 20 threads, 25MB L3 cache, 3.0GHz
•Intel Core i7-6900K: 8 cores, 16 threads, 20MB L3 cache, 3.3GHz
•Intel Core i7-6850K: 6 cores, 12 threads, 15MB L3 cache, 3.6GHz
•Intel Core i7-6800K: 6 cores, 12 threads, 15MB L3 cache, 3.4GHz

Now the 6800k - 6900k look like they will be updates of the current haswell-e lineup with minor in increases to the stock clock speeds (I.e. Two six cores and one eight core - expect the 6800k to come with 28 pci-e lanes ala 5820k with the 6850k coming with 40 ala 5930k). The 6950x represents a new tier for the enthusiast line given that the past three generations have consisted of three sku's
I have indicated previously (re skylake pricing) that Intel tend to be rather consistent with their pricing structure with new comparable cpu's costing a similar amount to the previous gen.
So Intel have two choices with broadwell-e pricing
1) maintain haswell-e style pricing for the lower thee sku's add a new price point for the top chip - expect at least a £200 premium over the next chip (so £1,000 +)
2) drop the price points of the three chips comparable to haswell-e cpu's so the new top end chip sells for circa £800 in the UK.
Given that Intel wont face any competition at this level and given that you could hardly drop the price of the 6800k below the current 5820k price without making it cheaper (from Intel) than the 6700k I expect option one will be likely.
( if Intel maintain 5820k pricing for the 6800k - resulting in around £300-£320 at retail in UK, then they will have to significantly move the price points for the other two 'k' cpu's from the equivalent haswell-e price points - 5930k £430-£450 and 5960x circa £800)
