Weight of a NuVinci 360 is 2450 grams versus a Rohloff at a max from what I can see of 1825 grams. Price ... $399 versus around $1,000+ ... Gear inches of the Nuvinci 360 is 360% versus 526%. Looks like the only box it ticks is price. I guess there are other options such as the SRAM G8 (over 2kg but no idea of gear inches) and Shimano as well including the Afline 11 speed which is coming out in Di2 mode soon. The Afline 11sp is 409% and http://starbike.com have it for €329 less VAT.
I also saw a post suggesting a SRAM DualDrive as another option.
