For context on some of the previous discussions, this is what Christoph Kemper said on their own
forums:
We are aware that the Profiler Player has the potential to serve the needs of very different users. On the one side there is the connaisseurs of pure amp tones, without the need for sprawling effect arrangements. On the other side there is the wish to play complex Rigs taken 1:1 from the big brother Profiler units. The Profiler Player has the theoretical potential to play full-blown Rigs. But I think it is understandable that we have not drawn a Profiler at half the price of a Profiler Stage but 85%-ish of it‘s featues.
Thus we consider since quit a while to offer one or two software upgrade (with costs), that will boost the Players features towards the Head, Rack and Stage.
The ability to create Profiles on the Player is also a story discussed by our team. There is a few issues to be solved, such as how to use the sole input of the Player for the return path and provide an A/B comparison.
The last paragraph is particularly interesting because it means they might offer a way to create profiles using the Player. That would give it more value because it would work for those with amp collections.
I looked at my used market recently and you can get a used Kemper Rack or PowerRack for only 150-200 € more than the Player, but the Player is much more compact and portable.
