Spy shots: Shimanos answer to XX1?

Most recently in the wide drivetrain news was the fact that SRAM had released X01, a trickle down group from their top tier elevel speed drive train. What was puzzling about this new groupset was the fact that it weighed just 40-60g more than XX1 and retained both similar features and the blindingly high pricetag! SRAMs argument was at the original equipment level X01 worked out far cheaper meaning complete bikes would be both eleven speed and fairly affordable. Where however does that leave the riders who, like me, buy a frame and either build it up with a custom specification or alternatively use many parts from their old bike to keep the cost down. The rumours are still circulating about XX9 and how soon we will see it being released however on Jared Graves' winning Yeti from the EWS at Crankworx Whistler something exciting was being tested. Although Graves appears to be using a standard 10 speed XTR mech (likely long cage) it's coupled up to what appears to be a 11-40/42 cassette (standard freehub compatible), providing similar ratios to XX1 but without having to replace the rest of the drivetrain! Even if cassette prices were similar to the prices SRAM are charging merely by making the system compatible with the existing shifting gear brings the price down massively. RRP for the existing XTR cassette is £209.99 (cheapest XX1 ~ £245 (Bike-discount.de) so even if it went up by another £50 it would still be undercutting SRAM massively! Some healthy competition can only be a good thing for the wide range cassette market although it'll be some time yet before we can purchase the Shimano offering. Although the lower 7 cogs appear to be of the standard XTR variety the upper 3 seem a very rough prototype - no doubt Shimano will wish to refine these further prior to releasing more information.
