For those who don´t need more reverbs, delays, pitch correction, etc. Purchasing the RackUltra FX Card only for a Saturator is a no go… so maybe add it to dPack? or maybe a reduced version of it… we need to distort things 
The plugins available on the RUFX require substantially more processing power to run. A&H cannot simply port the Saturator plugin to the regular FX slots because those slots cannot use the extra processing power that the RUFX card brings.
Furthermore, the reverbs and delays on the RUFX cannot be compared to the time delays available on the console without the RUFX. The normal time delay FX are some of the worst sounding FX available in a modern console (they aren’t even true stereo FX). The time delayed FX available in the RUFX are some of the best sounding time FX available in a modern console. It is a literal night and day difference between the two options.
