Instead of seeing the glass half empty, can’t you just see it half full?
Märklin does NOT plan to enter a competition with Hornby and co. Clearly the target isn’t the british market.
I'm not so sure about your assumption about Marklin not wishing to compete with Hornby ...
I decided to take some pictures with various combinations of H0 and OO items I have.
To start with, a Hornby Merchant Class loco - New Zealand Line from the R2300 Bournemouth Belle set - someone in this thread mentioned wanting a Merchant Class ...
The tender is correctly coupled to the loco, so no comments on the gap please ...

Next is a Hornby Pullman coach from the same set, coupled to the loco.
Yes the couplings are properly engaged, so no comments about how far apart they are ...

OK, it doesn't appear so in that photo, but the coach is actually the same height as the front portion of the tender. So the next thing to do is try a Trix/Marklin Orient Express coach, which is what I envisaged hauling behind Flying Scotsman in the absence of suitable British coaching stock.

The rails along the top of the roof are just under the height of the tender front, with the roofline about 3mm lower. So the next try is a modern coach ...

The roofline is near enough the same as the previous picture. Yes it is low compared to the loco, but it could work, but would be better with the Orient Express coach.
So the last test was to use a Marklin loco with a Hornby coach ...

Ta dah - the mismatch isn't as obvious as I thought it would be. The loco I had to hand is the Insider Br65 from a few years ago, and I would regard as reasonably representative of H0 loco size. This leads me to believe that using the Hornby Pullman coaches with the Marklin Flying Scotsman is probably a viable solution until Marklin produce models of British prototype coaches.
Finally while glancing around the magazine rack in my local Tesco I saw this magazine.

It is the February issue, and if you want a copy you will need to be real quick, as the new issue is listed as coming out March 1st.
