Shimano to Sram 1X11

Depends on the ratios of the double, but yes, I know what you mean.

The 10t feels like a big jump from the next one (dunno if it's an 11 or 12), I rarely use it other than on the road, and would personally forgo it for an 11t without too much worry.

That said... I did used to find myself in top gear quite a bit on the road on 1x10 with a 36t ring (26" wheels), with XX1 32t ring and 29" wheels I do find the higher gearing noticeable. I went out on a shop road ride on my MTB a couple of weeks ago and we averaged 21mph, and I still barely used the 10t sprocket.

From a sales and numbers perspective I would think it will be their primary product. I don't see many potential 1x customers being tempted away back to a 2x setup. I could be very wrong and only Shimano can tell us that a year down the line.

The OEM market is infinitely bigger than aftermarket, and I suspect doubles will still rule the roost there for a while, particularly with the more limited range.

I'm not sure I get the whole concept of 2x with Di2 apart from having the continuity with the rear

Do you mean the double specifically, or the Di2 bit? Di2 is just a different mechanism to shift, there's no concept really to get, it's lighter (at least on the road, not sure on MTBs) than mechanical, requires less effort to shift and just works perfectly every time. The sequential shifting is neat, but that's a by-product really.
The 'point' of a double is that it gives a far wider range...

OEM is a given so my assumption is based on aftermarket where consumer demand is more measured on the specific product.

It's the Di2 bit. I meant I do get it in terms of the marketing selling a complete electronic system and the engineering perspective and I like that Shimano have pushed this concept as this can only be a positive thing for future development but I don't see it fulfilling an actual need in MTB if that makes sense where as I can on the rear. Front shifts are hardly a big undertaking. I completely understand that as a concept you can't very well sell one end without the other as this would be suicide unless you purely offered XTR as a 1x11 option only as per XX1.

I don't disagree with what you're saying. In fact I completely agree. I would would just dissect the concept somewhat and use the parts I deemed the most functional.

Front shifts are where it Di2 makes most sense. With over shifting, trimming and timed for the ramps not to mention the sequential shifts and making power off for front shifts a thing of the past.

I agree, a front shift is more effort too, in fact in use, it's the front mech that's far and away the most impressive on Di2.
