I wouldn't count SVS or Hsu out in the areas where Epik and eD are competing. It will take them longer to respond if they decide to however.
That's one of the positives for the new guys, they can design and launch in short order. However, eD's supply chain and bottlenecks may eventually cost them...grew too fast, a good and bad thing. Epik has better control, but that could change too. Chad's working on those new designs, but frankly, I can't see how he can keep up with existing orders. I'm sure new launches will happen eventually.
I think both are a bit too ambitious. They should stabilize the existing lines and order fulfillment. Once established, then release new products. Stop teasing potential customers with possible vaporware that may or may not make it to market...they've each got enough on their respective plates. It may not be what we want to hear (silence), but IMO, it's better business sense.
