The thing about the gears though is that those are specifically unique to the Gomu Gomu No Mi. No one other than Luffy can pump air into their bones and muscles and take their devil fruit to an entirely new level. Yes Luffy's awakening will be something specifically unique to the Gomu Gomu No Mi as well, but ANYONE with a Devil Fruit can awaken it, just like anyone can awaken buso/kenbunshoku haki. Because its something that can apply universally among all DF users, I expect it to be something that we get more actual detail on before it just pops up. I'm not disagreeing with you on whether or not it can happen this arc, just feel like its too important to be something that we don't recognize the moment it happens.
