It's been actually quite dead in the last years about the modellers/multi effects. I think FAS and Kemper raised the game so high that a lot of manufacturers either went for really cheap solutions even using smartphones/tablets, or are working hard in R&D in order to follow the pace.
I think that's where we are right now, and that at some points all the Line 6/Digitech/TC Electronic/etc will release quite in the same time a bunch of new products. But when ?
