Noting that I don't really fall into that camp, the reviews I've read have suggested that Square/Enix hasn't especially succeeded in producing either on the schedule it's been working on now.but what do Final Fantasy fans really want: consistency or innovation?
I suppose if they're embracing the Unreal engine, there's some hope that certain problems that have to be re-addressed with every issue would fall away, but it sounded to me like they also needed to address that the last regular game barely seemed to have been made with player input in mind. If they regularly stamp out games in that mold, the result is likely to be spectacularly depressing for customers and their sales department alike.
