I would basically agree. Totally even. But, just hypothetically: What about all this being an incredible marketing stunt Christoph Kemper is pulling off? Just think of the editor, do you really think it wasn't possible to release an editor earlier? Then, from all I know, there's also been a huge reverb (and delay?) update. So, why is CK holding all these back for so long? It's certainly not a previous lack of programming skills. So it must be something else.
Not that I'd have any real answer to that question, but when you look at the price development of the Kemper over the last 12 years, I'm sure you will have a very, very hard time finding any digital device that held it's value even remotely as well. Heck, even outside of Corona, the Kemper prices went up here and there. And you can bet that with this new update, the prices again won't drop for a long while to come - with some new sales being created very likely.
So, while this is pure speculation, the entire story could as well be a prime example of most excellent marketing.
