Yep, but that happens with nearly all concepts.
Reason? Whilst the concept gets everyone excited, car manufacturers have to "pull back" the extreme design to appeal to a larger market... or so they think. What they fail to realise is that by doing so, they lose that special something that excited everyone with original design.
I picture it as a Samurai going into battle with a steel pipe instead of a razor sharp sword... sure he is going to do some damage but he really isn't all he can be.
As an aside, I really like the Mazda concepts and hope they don't "dull the sword" too much.
