No you don’t have to eat crow or anything unsavory. 
But digital hearing aids technology has advanced in the past decade or so. You are not denying that, are you? For me the digital technology advancements (over time) seems undeniable. And, one of the biggest driver for technology advancements is new/better/faster processors.
It take a lot of effort to install a new processor and then write new firmware and new fitting software to take advantage of the extra power/size/memory etc. So we should give credit where credit is due is all I’m saying. Also, the manufacturers don’t release everything in one fell swoop. Other advancements using the new processor are likely planned for the future.
Installing a new processor is much better than dressing up the previous platform in new cases, and then trotting that out as the greatest thing since sliced bread.
