OK but whoa lets be fair, the same kids can tell that the motion capture cgi in Polar Express isnt real either but if you mix it into a live scene in a nice way it can be as impressive as the war machines in war of the worlds.
I think expecting it to BE a trumpet as early as 2006 is kinda kookoo.
I think a more in-line comparison would be whats being used here:
http://www.patchmanmusic.com/mdt.htmltheres 2 guys doing demos on that page, one is a so-so player using the vl70-m which is the closest thing to arturia brass theres been. It uses a similar approach of acoustic physics modeling.
Theres another guy who is a way more fluent player but hes using reaktor. i think maybe hes using a physical model ensemble but i dont know.
If you can, imagine guy 2 playing the sounds of guy one. THATS why we are ga ga about physical modeling, not so much because we want to replace our trumpets or saxs but to have new instruments that share as many of those behavior traits as is possible right now.
Now, you might be able to fool some people with sampled brass, but to me that always sounds like a big static accordion synth with none of the real animation and personality of physics models.
You could edit together sampled clips and fool people, but arturia is on the road to a playable live instrument.
