SRAM X7 goes 10 speed which as the article suggests means that X9 and X0 will too.
I guess that Shimano must be thinking about it too - presumably SLX, XT and XTR to compete with the relevant SRAM ranges (I know - please don't post any links that'll get this thread closed...)
Good news I reckon. 1x10 (11-36) may well be feasible for me once I'm a bit fitter again.
