@vivi the mage Short version: We're aiming at having the new 5.0 before the holidays this year. That's not a promise, just our goal. As we get to around summer we'll know for sure if we will hit our deadline.
We're also looking into some kind of upgrade / loyalty system. We try to avoid a constant "discount" cycle, but we may (again, not set in stone) offer a pre-order discount to past customers. At least it is something I want to do, its more a matter of logistics and how we do it. Suffice to say, the answer here is I hope to provide a way to get our past customers into a shiny new 5.0. Maybe even discount extra base clasps so you can gift your 4.0 to a friend
