1x is not about gear range, it's about shifting. Front shifting doesn't work as well as rear shifting. Not anyone's brand, not any group. That's why the front shift is the big one and you keep away from it until you have to. Rear shifting just works. 2x is about shifting ratios. Doubles will survive as long as roadies want a corncob in the rear. I pretty much expect triples to disappear, though. The only reason they're surviving on cheaper MTB's is that the Walmart-to-$500 range is a very standard bike with very standard parts and the triple is one of them.
