I am going to make a purely speculative statement here.
The new cab will have the F12-200X Celestion driver. It is the only full range 'guitar' speaker that Celestion has in their lineup, so it makes sense to me.
If I am correct, it is likely possible that a DIY 2 x 12 or even a 4 x 12 cab with that driver will get the Kone effect to work exactly as expected in the 1 x 12 Kemper cab.
