New tech companies will make media noises in two cases:

1. Need investment

2. Have a product to sell

Currently carbon nanotubes firms/departments fill neither case. They have enough money, because of all the hype and they don't have a product, as there's still no known way to mass produce.

In a few years, once price efficient nanotube fabs come online, IMHO we'll see tons of amazing, ground-braking products out.
