Though I like the skeuomorphic approach in the UA plug-ins, I wouldn't want to see Fractal go the same route. For one thing, specific amp and cab models are just the starting point when I'm making a patch; If I open Neve 1073, Pultec and LA-2A plug-ins at the same time in UA Console, they remain just like three distinct rack units, patched in and individually modifiable, but distinct nonetheless, exactly like their real-world counterparts. But in the Fractal, everything is integrated; most of my patches are hybrid mutants, rather than faithful reproductions of a single brand's amp/cabinet combination.
Also, think of the complexity that the Axe architecture would create in an attempt to do this. When I choose an amp model, I've got eight layers of control pages for that amp model, some with a bunch of knobs and drastic interactivity. That kind of depth has no real-world, iconic visual corollary, at least not one that people know well enough to justify the Skeuomophism. Sure, it might be fun to switch from a Bogner to a Marshall to a Boogie and watch the faceplates and knob styles change, but if you go to the Preamp or Power Amp pages, are you going to be looking into the back of the amp? Into the guts? And even on the Basic page, there's the whole copyright issue; most of the amp model names are disguised for a reason. Do I care enough about seeing Vox fabric on my AC30 in order to see Fractal having to pay some company money to cop their Logo, money which could've been spent continuing the consistently amazing parade of updates and improvements?
And don't forget that--unless you're an Ax8 user, you've got the possibility of four separate amps, cabs, delays, etc. in a single patch. I built a patch tonight for an upcoming sub gig that runs a 5153 100W Red simultaneously with an Angle Severe in the same scene. So should we be looking at a Seinfeld's "Pigman" style mashup of the Engl and Peavey logos? And that's just the X sides...
Lastly, I've had my Axe-FX II since System 5 or 6; I'm really, really used to tweaking the controls with the current layout. I don't want to waste time adapting to a bunch of slightly different layouts to find the same controls.
That said, I agree with h.c.e. about the superiority of sliders. I hate turning knobs with the awful Mac "magic" mouse. I generally just hit the textbox above the knob and type in a value in order to avoid the whole up/down/around knob-turning process.
