All previous MH games worked fine on PSP or to be exact audience was fine with just one analog.I doubt that Capcom demanded "second analog or else",this is most likely Nintendo idea fueled by 3DS second analog redesign(probably fueled by Vita arrival,nothing else makes sense to me).
MH is not just some game in Japan and Nintendo surely wants more MH on 3DS so second analog will be used in sequels too.Nintendo would have to be totally insane to push this ugly mess for the rest of 3DS lifespan,like totally batshit crazy.What is next then,rear touchpad addon?
Not to mention that this is adding extra confusion to already confused developers.
This ugly thing is a stopgap designed to please existing 3DS userbase,nothing else.Redesign will be made and games will require second analog,got old 3DS--buy Frankenstein addon...ugly as hell but it has second analog functionality
I refuse to believe anything else.
