I don't have a detailed timeline with Otter 3.0, the scope appears to continue to creep (but, perhaps in a good way ). But it's still looking on track for early next year.
Probably the best thing to do is to get in touch with our sales engineering team, so we can learn a bit more about what problems you're trying to solve, and can give some more details about how Otter 3.0 will help; they can at least show you what's upcoming, so you can better decide if it's a good fit.
