In the end, its about the muscle behind the game. The DQ series was never about high end graphics engine or extreme polygon count models. Don't get me wrong, DQ10 will be a higher texture, double the polygons of DQ8. But those who played DQ8 knows that is not saying much.
Final Fantasy on the other hand, every since the FF6, has been their (Square) graphical impress the hell out everyone game. So that game was gong to be on a HD console game no matter what happened. Why, because they love to push the boundaries on consoles to present the most intense graphical seen game in the series.
Bottomline, you will always have two camps, those who are looking to blow people away with visuals and sounds and others who are trying to bring entertainment to the masses without having a high polygon count.
The real question is, which camp is a Kingdom Hearts game in? Does it want to push the boundries of graphics or does it want to be a lovable game that all can play and not worry about mind blowing graphics?
I'm just saying...
