I think the new Fenders are basically, analog solid state amps. My guess they took the idea from Peavey and Quilter, but using their own unique voicing.
One of the biggest issues with solid state is the confusion between digital modeling and analog circuitry.
Many agree analog circuitry does come close to tube amp tones.
Digital modeling is in the ballpark, but rather unreliable, often finicky, and puts many users in tweaker paralysis.
Both are often put in the same camp. To me, that's like taking a fully hollowbody with humbuckers in the same category as a solid body single coil guitar. Sure they are electric guitars, but they are not the same in sound or functionality.
When everyone above mentions the different tones, articulation, bloom, etc.. of a tube amp, the problem is most people cannot turn their tube amps up enough to get the power tubes to react that way (most of what everyone is talking about is related to the power section of a tube amp).
So to many solid state amps, analog or digital fit the bill because to their ears (and I will say my ears too), the non-tube amps sounds the nearly identical because we cannot turn tube amps up loud enough to really hear the difference.
I think that is why solid state amps are the getting more popular, even among the pros.
Not to mention, when in a band environment, I think the nuances of tube amps is lost with digital effects, compressed processing, and digital recordings.
