Shimano new Dura Ace releases ?

[masking_agent]

Hi,
I didn't see anything about Shimano Dura Ace's new 12 spd electrical at the Eurobike show. Anyone know if and/or when they will be releasing ?

I don't think I've even seen prototype photos out there yet, have I missed something?

The 9100 series only came out mid 2017, so I'd expect another 12 months at least.
