After getting it all on the bike and updating firmware I can confirm the following setup works with 6770 derailleurs and STIs:
- SM-EW90-A, junction box for shifters and charging point
- SM-BTR2 battery pack
- SM-BCR2 battery charger (and e-tube interface)
- 2 X EWSD50 to connect to the shifters (one to each side) as the SM-EW90-A doesn't have the inbuilt cables of the SM-EW67AE
With SM-BCR2 I was able to run Shimano's e-tube project to update the firmware and enable multi-shift. Couldn't have been easier.

The RD dictates the number of total speed for the system, so the answer to this question is a "Yes" but it has a contingency. You have to update to the latest firmware (multi-shift compatible) in order for the 6770 shifters to recognize the 9070 RD. Non of this is "officially" compatible, by the way.
Turn down the suck knob.
[quote="bonafide"]Repeat question: Has anyone yet tried the 9070RD with Ultegra shifters & FD???]
Unofficially speaking, you "can" get it to work but it is not recommended as the 6770 FD does not have the micro-adjust feature to allow micro-trimming of the FD to accomodate the extra cog and added FD cage travel/movement. Again, Shimano is not, will not, and has not suggested this as a compatible combination of components - experiment at your peril/non-compatibility.

Could be used as a cool 1x11 setup for a CX bike though
New firmware for Ultegra Di2 6770 just came out. Dated April 9, 2013, description is "enhancement of function" and for the battery mount dated March 26, 2013, "Improved stablility of unit communication, Enhancement of energy-saving".

None of that is needed if you go with this http://www.ebay.com/itm/290894523169?ss ... 1555.l2649" onclick="window.open(this.href);return false;
