Refreshed Olympica Nova incoming?

Olympica speaker are great speakers. I used to own them and have heard upgrades between them and Nova. The speakers are as @rick_n said high end products and have long life cycles. I would consider picking up a pair of those discounted ones. New models are likely to cost a lot more. They are likely to be relatively small tweaks to sound better. It would be easy to get a six year old speaker and enjoy it for decades. 

One thing to bear in mind, is Sonus Farber is now part of Bose. So I believe that Bose will employ trickle down technology, marketing, and profitability margins. 
In the their purchase of SF they also acquired McIntosh and there have been upper mgmt changes made there already. I already own a set, but if you’re wanting to purchase the sound, dependability, and reputation, I’d buy off the shelf or the current product roster. Known is a wiser investment than what might be. All my opinion of course.

I’m seeing more rumblings of this on Facebook groups. Will be interesting to see what comes! Definitely a camellia midrange driver..

I believe the Nova series debuted 4th quarter of 2018. My advice would be to wait on a new model. Many improvements have been made with Sonus Faber's entry level speakers. The mid level Nova series needs improvements in bass quality/details, dynamics micro/macro, cabinet resonance and to be less demanding on amplifiers. Yes, there could be a cost increase but the refinement could make the current series obsolete.
