Kemper is just trying to react to their falling position. They have felt they don't have to do anything as they dominated their niche until 2021 when the QC released. They just got lucky that the QC had so many issues, and was pretty expensive so it didn't straight up dominate the modeler market, even if it is still the top seller in its category.
The Kemper Stage released a few years too late for what it is, considering people had been asking for a "floor Kemper" for years already.
Kemper's "Liquid Profiling" feature is a kneejerk reaction to the QC captures. On Kemper forums afaik they were experimenting with this years ago but never released it.
The Kemper Player is another product that would have been successful if it came out in say 2020 instead of at the end of 2023. It must've taken them at least a year or two to develop the Player (you don't just "slap" something like this together), so if anything it's most likely another response to the Quad Cortex. "Hey, here's a capture player/multifx for much less money than the QC!"
What they didn't account for is the rise of Tonex and NAM. Now there's not a whole lot of reason to buy Kemper for the average person (rather than the gigging pro) that drive the sales numbers. You can get Kemper's #1 feature for 177 € in a Tonex One. IK's crap software and Tonex One's limited functionality is far less of an issue at that price.
