I wrote down the spare part price for Sinus motors a few years ago...
You can still search them too on Google, some dealers still have them in stock.
214168 Large Sinus motor + Decoder (Re460-specific) = 160 Eur (incl VAT)
230592 SDS motor for ALL 4-axle pwrd locos = 60 Eur (incl VAT) -- some dealers still have it for 40 Eur
213479 SDS motor for steamers /2-axle pwrd loco = 96 Eur (incl VAT) -- I think it used to be 80 Eurs, but Marklin price went up in the last year
102375 PCB SDS for BR218 (model specific part) = 90 Eur (incl VAT)

The answer is simple...
Firstly, everything that MFx can do, DCC can
always do it better. Matt has highlighted some of these on his posts above.. Loco auto-register? Railcom Plus can do it in a matter of seconds...
Secondly, as already mentioned above too, customers will also be isolated by the plethora of more options available in the DCC world.
A few years down the line, DCC users will look at MFx, and laugh.... "So Marklin MFx can only do that much? In this day and age? LoL!"
Additional comment to the previous:MFx was not a proven technology when it was first introduced in 2005/6.
The fact is the first MFx decoders are made by ESU - there were some kinks at first. But after ESU fixed them, Marklin decided to go alone with it..
... which create more bugs...
I haven't bought any new Marklin so far, but it look like from what everyone posted, they have finally got it right.
So not unlike other Marklin "innovations", customers again become guinea pigs for their long winded experiment, until they got it right.
... that leaves a sour taste for many...
End of Additional CommentsFinally, a quick review for business strategy wise...
Which one would be cheaper, more innovative, and would provide a better result?
Create a new look-a-likey system to DCC from scratch, then painstakingly try to compete feature-to-feature with DCC.....(and still lose out)
...OR....
Create Marklin DCC+ by adding interesting features that are exclusively Marklin...
Marklin DCC+ would have less bugs to deal with, as it is based on proven technology, unlike Marklin MFx from 2006 - 2009 period
they would also have been cheaper to manufacture (arguably cheaper vs MFX adventure),
if they make enough innovation, they can compete to make inroads against Zimo, ESU, or other brands,
M* DCC+ can also place their Trix DC brand better...
... and to top it off, Marklin DCC+ would still be the dominant decoder in Marklin world.... since unlike DC loco, every AC loco will need to come with decoder by default.
