I heard about it from a buddy. I would think that FP may not have blasted it to the field staffers simply because it may be a unit that field staff wouldn't use much due to their access to more expensive calls with more features
I would guess it's because they've added a couple new features. For example, the Patriot has the same caller as the Inferno. It has a new remote though. One with buttons that are much easier to operate with gloved hands.
