All they are saying is that they are trying to get cutscene if across to you without pulling you out of charecter as much.
I must admit I thought ME2s QTEs were among the few examples of well done QTEs, they werent pass or fail so you have to repeat everything, and genrealy were half way through a conversation anyway so didnt disrupt flow much. The changes I'd make to the convo system include making at least some conversations time dependant, as in Alha protocal (so much wrong with that game, but its convo timing idea was pure gold), and on a few occasions the written option needs to coincide more with whats actually said (a sin not unique to bioware games sadly).
Indeed what U'd hope from this is making convos allow you at least in some cases to perform other actions, and to take account of what you do, changing the conversations course and awarding renegade and paragon points, have the charecter comment on whats going on.
