Maybe that has to do with their fit-bike than with a road-intended product?
Linked to the Di2, precursor to automatic shifting to maintain a power output range.

Well, I’m going to set mine for 500 watts.

Please provide pictures of your quads, then I’ll estimate how far you can go

That actually makes a lot of sense, but not likely for the reasons you may be thinking. I think they said it in the article, but if not, I think it’s really for commuter bikes. An automatic transmission probably doesn’t make sense for a race bike, but for a commuter bike, I can see the value. One less thing worry about. At some point, this stuff will all become just a commodity. Even the core “cost” of Di2 is not the parts. Not even close. The basics are just stepper motors. Cheap. It’s a recoup of development costs. Di2 STI shifters are - without question - cheaper from a parts & materials standpoint than STI.
Mass produced - and with only modest accuracy requirements - a powermeter system to drive an automatic transmission would be quite simple. And likely VERY profitable.
Shimano are already in the game with Cyber Nexus. It’s a Di2 city groupset, launched a year or two before Dura-Ace Di2. It’s key selling point is automatic “CPU” shifting.
A series power meter would be a good addition to Shimano’s product range so it’s no suprise they have been working on something for a while. Perhaps something is on the way in the next year or two. It’s a bit tenuous but Sky’s close relationship with Shimano could see them as a potential launch partner.
Talking about Stages, Tim Kerrison highlighted being involved in product development as important part of their partnerships. What doesn’t completely fit is that the Sky/Stages deal is for 1 year. Historically power meter development cycles have been a lot longer than that.

Ah, so what we really need to complete the picture are ANT+ sensors in the elastics of your shorts to measure your quads.
Wonder what the price would be?
Someone made an interesting observation that the pictures in the patent filing are of the previous generation DA, which might lead one to believe they have been working on this for a little while now. You could be right about the next year or so. Lots of players in the powermeter game now. I wonder what R&D SRM is working on these days.

And it would likely shift to maintain a preferred cadence, rather than power.
Though I remain excepted about the prospect of shifting logic that can cause me to maintain a certain power =)

And it would likely shift to maintain a preferred cadence, rather than power.
My preferred cadence would increases with increase in power. (from ~85 @ FTP to ~120 @ 1200W). So it would have to take into account both for me.
Right, ideally it would have a preferred power/cadence curve.

We’re going from chippin’ cars to chippin’ bicycles. The wonders of technology!
