You're giving Banshee too much credit, both for innovation and design quality.
note: i didn't give them credit for quality. i had a couple of warranty issues on banshee frames (both of which were handled really well)
maybe, wrt innovation, but i don't think so
Yeti (ASR5)
slack sta
Intense
yeah, intense nailed the ss, but its worth noting that the ss may have been an accidentally great am/trail bike as it was intended to be a slopestyle (hence the name) bike (which is why the large fit like a medium) - sort of the way santa cruz accidentally made a great burly trail bike when they were designing a 4x version of the blur
Cannondale,
steep hta
Norco
the new range has some pretty progressive numbers, but it was late to the game to be considered innovative (also, actually sta is quite a bit slacker than listed)
Rocky Mountain (Altitude)
short tt
Kona (lots)
kona is pushing progressive geo HARD but only in the past few years - not sure his name, but their new designer killing it, batting for average and power
the bikes/companies you name all had some cool innovative geo ideas, but none of them put it together like banshee did with the original spitfire and the new rune: long(er), steep(er) sta, slack(er) hta, low(er) bb. i never rode one, so i can't speak for the suspension design, which i know you and many others really disliked. but fwiw i rode a v1 rune for years, and while i can appreciate the v4fb (or whatever) dual link design wasn't for everyone i got on quite well with it
