Ok, before I even start, let me say this: PLEASE don't argue that FFVII is really being remade for PS3! The only proof of that was the tech demo which was just to show the PS3's power and draw people's attention to it, nothing more at the moment.
Now onto the topic, lets say Square Enix DOES decide that they would remake FFVII, but in doing so, they would lose time for future original FFs for a LONG time (lets say about 4-5 years). Would YOU prefer them to go on and remake FFVII with nothing but graphic improvements and better sound OR would you rather have them work on a FFXIII?
