Like everything in life, things that look better, attract people. It does not matter if it is your spouse or the place you live in. Hiding all the cables, integrated handlebars, etc all 'clean up' the bike and does make it look better. Bikes are getting pretty difficult to work on so the average person that can afford a $15k bike is probably not working on it. Electric shifting sure got rid of a lot of cable issues and once dialed in, there is nothing better when it comes to maintenance.

I like to do simple stuff at home and I like the feeling of being able to do them. Still, I've no interest in going to deep in the maintenance part. This is to say that I'm fine with the trade-off more integration means having to go to a bike shop for maintenance.

What I'm really not fond of are proprietary parts. Wanting to change a stem and not being able to find one that fits.. oh come on!! That for me is a no-go. Another important part is serviceability over-time. How long will shimano service this new group? Are they going for the 10-years time window availability of replacement parts?

I'm even ok with spending high on a bike (it's the price they charge, I'm either okay with paying it or I'm okay not paying it - my choice) but don't tell me I've to replace gruppos in 5 year time just because I can't find a replacement part for a derailleur or lever. That I consider unacceptable. I know european law is trying to enlarge these requirements for most eletrical products - bike related products are still not included in the already approved laws.

Why sram etap particularly? I'm asking because I have it and want to be prepared for some future difficulties.
Try to find a 11sp eTap junction box. Basically as soon as AXS came out, supply and support for it disappeared. Only options are to find one used (with high-ish failure rates, this has also become challenging) or to repair it if they know how to work on electronics. Instead of making the new junction compatible with the old groupset or producing a few replacement units, SRAM instructs people to upgrade the whole groupset.

If not from Shimano some aftermarket brand will probably do one

The wife and I both use the Ultegra CS-R8000 14-28 cassettes, but we are niche users as this was primarlily targeted for junior racers under the age of 18 who are limited to 7.93 meters (26’) of development. I suspect that for 9200, instread of a the typical 52x14 combo requiring a dedicated cassette, Shimano is expecting juniors to pair smaller chainrings with the wider range cassettes.

RD spec listy:
Top sprocket_Max. 11T
Top sprocket_Min. 11T

So maybe it is no longer designed to handle a 14t starting cog.

I know this is a DA thread but RD-R8150 sets 14T as the max top cog, which means Shimano still seems to have a plan to release a Ultegra grade 14-28 (or bigger) cassettes in the future.

as for someone in my environment has a group of 12, I will buy a Chinese cassette of 12 (if the spacing between cogss is the same) and see if it can be made to start with a 13/14 cog

Thx for the reply's about the 14cog question.
In Belgium u17 riders use most of all 48x14 and u19 worldwide 52x14.
that's why I asked the question, because i have two sons who are competition cyclists.

So how many people are planning to run the optional wire from the shifters? Is it confirmed that the battery life doubles by doing so?

I don't mind running an extra wire before the BB is installed.

Weight wise, it looks like no wire is lighter: 2 x 1.8 grams (CR1632 batteries) vs. 16 grams (1600mm EW-SD300 cable)
