Upgrade from Prime 2 to Prime 4?

I refer to this thread in this community:

There’s denon dealers that seem to believe it’s being discontinued. Thomann’s has stopped selling it, as has Sweetwater. It is still for sale, but it’s been discounted in some places (if you can even find it)

Prime 4 likely won’t be discontinued first, it’s the flagship product. inMusic has various other two channel controllers that appear to fit the market demand better.
