I'm curious to see how it sounds. I'm curious to see how it performs with third party IRs, which is a pretty hefty chunk of the sound quality dilemma when it comes to their products before. I'm interested to hear different tones free of effects. It looks like it can be used into a power amp as well, so there must be the ability to turn off power amp modeling. Finally, it looks like it will be released with a software editor, which means a studio person would be able to get the rack version and skip over the floorboard.
But mostly... I'm interested in why the marketing seems like a tempest in a teacup. It's supposed to be available in roughly two months. If I were releasing a ground-breaking flagship in the product line I'd be doing a whole lot more to release some convincing recordings in different styles. Then again, maybe it's just a bit early and they're trying to build it up.
Either way, since the demos don't seem to really highlight realistic use of the unit (dry guitars in recordings, using non-Variax guitars with third party impulses, etc.) we really won't know what's up yet. Interested though!
