I'm only going to jump in an offer an opinion, I got no dog in this fight either way..
It strikes me that you are being a little presumptuous in asking QXM what their Enterprise is made of.
Would you expect Pepsi to tell you their formula, just because you asked them nicely?
Or "Hey, KFC, if you don't tell me your seven herbs and spices, you don't care about your customers"
If they say it's not a recast, you have to take them at their word until you have one in your hand and can refute that claim. Consider that the design of the refit is well known and if you add 2+2 and get 4 and I add 2+2 and get 4, it doesn't mean that I cheated off of your paper.
If they say that they've got a prototype that is 5 years old and hasn't sagged, well, I might like to see a picture to verify, but I feel that still won't satisfy the hardcore detractors unless QMX can produce time lapse video of the whole 5 years.
And lastly, if QMX doesn't care to name names, then maybe they shouldn't have brought that point up, but I think the point that it's not just them picking a price out of mid-air, but seeing how the industry would price a simlar item is a valid one
Once this item is in the consumers' hands, then you can judge for yourselves whether it's worth the money. I'll be first in line to read such a review. Until then, tho, you're just spitting into the wind.
