@dahgutone its not going to catch cuz it cost more then most fat asses are willing to spend on an entire bike.

The thing that impresses me is that its got a sensor for cross chains..

It recognizes that there will be chain rub and moves the front D to accomidate the chain rub

i've got dura ace 7900 and it is usually very good. better coming down the chainring than up though, especially in the lower 2 gears. it's been adjusted but it's never perfect. in fact, i've never had perfect gearing. this looks like the solution and will be on my next bike.

@dahgutone Consider it more like a paddle shift system like in a Ferrari or the Nissan GT-R to keep the Japanese theme. It isn't necessary but it is technically superior.

Whether I'll need it or not, I'll definitely purchase it if I have money.

All the people complaining about Di2 have obviously never ridden it. My advice - try it out and then see if your criticism holds out.

Just another stupid gadget that cyclists don't need.... like index shifting!

[KneelArmstrong]

You lose front derailleur first and then after a while you lose the rear, so you get a sort of warning once you no loner have front shifting, and its a long warning like 500km worth of shifting on the rear left.

It doesn't justify changing from mechanical to this. Maybe when they figure out how to use the pedaling motion or wheel spin for power and loose the battery... Even then it would probably be heavier. I only see this getting use on TT bikes but even then most TT bikes have internal cable routing.
