For them to have a good demonstration, they would actually have to have good styles and sounds OOTB. Every other arranger demo from any factory merely shows how good the thing sounds when YOU get it.

Korg do not demonstrate the PA2X using third party loops and styles, Yamaha do not load up the sampler with audio loops to sell the T3.

I'm afraid that, were there to be a REAL 'factory demo' even using a decent player, all it would likely show is just how much MORE you are going to have to do to it, just to get it to sound as good as a 'closed' arranger...

Were I Dom, to be honest, I'd leave things the way they are, and let those with more 'dreams' than a sense of reality continue to purchase the MS, and find out the expensive way how hard this thing is to use

Me, I'd probably just suggest to anyone thinking about it that, if they haven't ALREADY created a bunch of REALLY good styles for whatever arranger they currently have, what are the odds that they are suddenly going to be able to do it with an MS?
