The group is so not outdated .. its e-tube unlike 7970 which means all the latest stuff works so you are safe at least till Shimano releases next Di2 offering maybe in 2016. You can even 'upgrade' to 11 speed by just buying the RD; everything works the same way.
But thanks to #buyer thinking like that I compiled a 6770 gearset for £250 its a bit 'sell sell sell' atm
