No it's not that simple, you can use 6870 parts. You just need the right junction box and battery

from http://carltonbale.com/shimano-di2-everything-you-need-to-know/ :

Synchronized Shifting and Bluetooth Wireless Units can be added to all
E-tube Ultegra and Dura-Ace systems but the battery has to be upgraded
to the BT-DN110 Internal Battery or BM-DN100 External Battery Mount.
To add Bluetooth capability, a EW-WU101 or EW-WU111 inline transmitter
must be added to road bikes and for mountain bikes, the SC-MT800 or
SC-M9051 display/transmitter unit must be added.

So @Shroom you can just about do anything, but it all depends on what parts you have and how fancy you want everything..

i have the full 6870 groupset. So, what exactly do i need to run loop/flat bars? the first one you linked looks good, XT shifters

according to the shimano compatibility chart you can go in 2 directions:
1. Just buy the SW-M8050-L + SW-M8050-R (XT shifters) and just operate your front and rear derailleur separate.
2. Sell your currecnt (cockpit)junction box and battery. And buy a SC-MT800 (cockpit)junction box and BT-DN110 internal battery (or BT-DN100 if you want to go external) together with just a single XT shifter.
If you can sell your 6870 junction and battery for around €130, both options are about the same price.
