Good one... Also:
Because as cool as the II is, lots of other units out there are actually quite good as well
Because plugins are improving rapidly and are much easier to replace, drop in, and cheaper.
Because some people may have different requirements with regard to weight/portability/foot control.
Because some people find their familiar units are good enough.
Because some people don't want to "tweak" and want a simpler unit
Because people have a setup that works and they don't want to fix it if its not broken
Because some people simply do not want a modeler.
Because some people enjoy the tactile aesthetic of more traditional gear.
Because (gasp) some people actually think a different unit sounds/feels/plays better
Because someday there will be an AxeFx III, Kemper II, POD HD++, 12 Rack, etc.
<etc,etc,etc,>
As a Fractal fan, I share your excitement regarding the new product but the the kool aid around here is getting pretty f*cking thick. The G1 units were the revolution. G2 is the evolution. Actually the POD was probably the real revolution.
