With compact cranks supplanting triples in the road market and 2x10 drivetrains displacing triples in the mountain bike market, I'm not holding my breath that sufficient demand exists to get Shimano's attention.
Note the Erikson tandem used a Di2 rear derailleur with modified, longer cage to allow the use of larger cassettes. Perhaps the after market will hod-rod a Di2 front derailleur at some point?
