I'm often wrong, but I don't expect a vst/au/aax plugin to replicate the AxeFx's modeling. I expect something like an AxeEdit plugin to increase functionality. There are various ways this could be implemented, but I expect it to be like the UAD method where the processing is all handled by the proprietary hardware to keep the load off the computer. The amount of processing needed for the amps, etc. seems like it would overwhelm most host processors as to render any DAW and all the typical plugins associated useless. Even if it was stripped down to a simpler version, they already dedicate one of the tigersharc processors just for the amp models. I could be totally wrong though. Maybe they have coded stripped down versions that would run standalone or as plugins off host processors.
