Thanks for your interest! The Eris family has been a big success for us and we're glad you like it, too. Unfortunately, we aren't able to "pre-announce" any products that we may have in the works (Eris or otherwise) for competitive reasons. Pre-announcing a product too early in its development is very risky as it can give other manufacturers a head start on designing and releasing a competing product.
We're working on a lot of exciting stuff over here, but we hope you understand that we can't announce anything we do before the time is right.
