I really hope it's going to be eTAP. That would mean that my next bike has precisely ZERO visible cables and wires. Plus, since it's gonna be a flats racer, a single aero oval chainring by absoluteBLACK will suit me nicely.

For eTap it's just a software update, and you can bet they'll introduce it at the top end.

AFAIK their mechanical shifter internals are all identical, so they'll just have to upgrade the right hand ratchet - also a simple upgrade. If the derailleurs stay Exact Actuation, they don't need to change either.

There will need to be an eTAP (RED?) RD with a clutch to prevent the chain from dropping.. At the moment the 3T Strada bikes of Aqua Blue Sport use Sram Force 1. Mechanical shifting..

Not for 1x. No way are they going to release an eTap 1x derailleur that doesn't also have a clutch, 12t narrow/wide pulleys and a straight parallelogram body.

So far Sram has said Etap and clutches don't play well together. That's why we haven't seen an Etap MTB group yet despite years of waiting. Weird though since Shimano has no problem getting their servos and "damage control software" to work with the clutch.

Hmm, probably true, they won't admit that road 1x doesn't need a clutch. Shame as it's obviously useless but adds 100g.

I would guess that the 1 x 12 controls and brakes will be based on the new etap HRD lever shape and brakes - why wouldn't it? and a clutch rear derailleur...
