Eh, Armani is just trying desperately to remain relevant. Amongst fashion fans, Armani isn't highly desired. Amongst fans of sartorial style, Armani isn't highly desired there either.
SO, I think he's just trying to be provocative because a part of him knows that anybody who OUGHT to be listening has long since moved on. And, he's trying to entice groups of incredibly noveau riche who aren't particularly stylish (Russian billionaires et. al) and who still think that wearing Armani will thrill everybody in the room. Unfortunately, the guy in the G&H has already done that, so he probably finds himself lonely in the corner.
As for Savile Row's stodginess, they always seem willing to work with different fabrics or fabrics brought to them by their customer. It has always been a challenge that they've accepted well. I remember reading an article once (I can't remember which tailor it was from, though) who talked about having a customer bring him yards of beaded sequin fabric to make into a dinner jacket for a 50th birthday party or something like that. So, Armani is wrong there as well.
