Yes folks, we have entered new realms of crazy in the mountain bike world. 11 gears.
It was only a couple of years ago that everyone thought we were going to have 3x10 gearing, but now 2x9/10 is becoming more popular and if you have the legs for it, you can go down to 1x11, SRAM's new drivetrain.
With this you can now pretty much get any number of gearing you want (within reason of course) on any mountain bike.
Carbon cranks for the XX-1 set might be a bit expensive though, so I'll wait for it to trickle down the range perhaps next year.
