I’m sure it’ll show up
I’m sure it’ll show up on some TT bikes – that’s the only place the technology has an obvious advantage, the reason why many TTers persisted with the Mavic systems: you can put the shifters wherever you want them, and have more than one. Given that a Pro only has to have gears that behave for five hours or so before they’re once again in the hands of a professional mechanic, it’s difficult to see what the advantage is, really. Might be good on bikes with particularly tortuous cable routing (the S2 has) but most pros will stick to cables i reckon.
