Vlado, I understand that you're disappointed. I'm sure you were hoping for a community thrilled and happy about the merger.
I can only speak from my own point of view, but for me Corona was the very thing the archviz scene needed. I was using Vray from the beta days, and I was loving it, but as time went on, more and more issues started to show up, and tbh, it felt as you shifted all your focus from archiviz, to vfx. Also, the way the software grew... it just became increasingly cumbersome to work with.
Then Corona showed up, with a very fresh approach, and they truly seemed to understand the artist's point of view. I switched over one afternoon and never looked back. The software just delivered in every aspect and made my proffessional life about ten times more delightful. (Not to forget: At a very reasonable price!)
And what's most important: They brought competition. Which is extremely needed in these cases. Look at ADSK... the latest 3dsmax release is a joke! Complete stagnation. All they do is milk us of money through subscriptions.
So now, when I hear you're taking over the show.. I fear Corona's days are numbered, and that makes me sad and angry. Why? Because we've seen mergers like these before. Initially, the talk is all sunshine, and dev teams will go on, and that no product will be sacrificed etc...then fastforward 2 years, and the story is very different. Especially in this case, where the products are so very similar, and the user group is practically the same, I can't see why a company would want to use resources for some kind of parallell development. Then we all know Chaos will not scrap Vray...
If I am to be optimistic, we'll see a fusion of the two renderers (Corona's simplicity and foolproofness, with.. whatever benefits vray might add) and that you find in your heart (and wallet) to sell it at a decent price.
If I am to be pessimistic, you'll pick whatever tech Corona has that you miss for Vray, then discontinue Corona completely. Then hike the price of Vray further, since you have all this new and cool features.
It's up to you (or your investors?) to deciede. In the meantime, I'll just hope for another challenger to appear. Since this business badly needs good competition.
