I wonder how much of this is just bedroom hacks (like me) feeling bad that it wasn't something ultracomplex and powerful they could buy to feel superior. Maybe some weird subconscious gatekeeping, because fas is putting out a simplified product that might have mass appeal.
I think it is sort of natural to expect a company like Fractal to have a consistent "we're always going to be the complicated do-everything company" but really... this VP4 makes total sense business wise I think.
1. How much further can you really go in terms of amp realism? When the general public puts an Axe3, Quad Cortex, and Helix side-by-side constantly on Youtube and the like, and comes up with the inevitable answer that "they're all good, they just sound different" ... any further enhancements are really just a matter of perfection. But never let perfection be the enemy of good. IMHO.
2. There's a huge swathe of people out there who don't use modelling. Forums like this one and TGP are more or less echo-chambers where most people are digital enthuasiasts. But a fuck ton of people out there are not interested in modellers, and even if they are, they're not interested in spending $1500+ on a modelling solution. The VP4 is for those people.
3. Cliff already said it, but this product is for people who play live. Again, a lot of people on forums do not play live, have never been in a band, never toured, and never really leave the house with their music. I'm not besmirching that, and I have no problem with it. But it is a fact of life. Their experience colours their perception of products like this. But I'm telling you, there is going to be a significant proportion of people out there who have been waiting for this.
Axe3 is too cumbersome to use with a valve amp. FM9 requires too much floor space. FM3 isn't optimized for it and doesn't have enough switches. This is a sweet spot pedal I feel, that Cliff and co are well aware is going to be used on boards full of analog drives and compressors, GigRig type loop switchers, and all sorts of configurations like that. It is explicitly NOT a product for your average Youtube guitarist.
IMHO, YMMV, m2p, etc etc.
