One thing stuck out to me in the Gamespy article:
When I was looking at Shogun's combo list yesterday, I noticed it said something like 'level 3 muay thai'. Our created fighters might start with bare-bones techniques in our disciplines, and actually have to build up their skills by training new levels in those disciplines, like the aforementioned first-level kickboxing lesson. Presumably it would be a while before we'd have all the tools someone like Shogun or Chuck has.
I read before that we could do training and such in career mode, but I figured it'd just give a small boost to the related striking skills or whatever. But it seems like we might actually have to train higher proficiencies in our disciplines to get more techniques and/or combos, which I think would be a great idea.
