If you have an RPG with an expansive real-time full scale world map that needs more than 8.5 gigs, then splitting discs won't work too well.
In FF7-FF9, the world map was duplicated across all CDs, and then unique cutscenes were put on each individual disc.
But the GTA IV developers were running into size constraint. It would be annoying to change discs each time you wander to a different part of the city.
So yeah, I think Blu-ray will be eventually needed. I think in a Nomura interview, he mentioned of bringing back the flyable airships back in to FFXIII / FFVXIII, like the pre PS2 era. I'm hoping to do some airship flying with the six-axis.
"Naturally the common people don't want war: Neither in Russia, nor in England, nor for that matter in Germany. That is understood. But, after all, IT IS THE LEADERS of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is TELL THEM THEY ARE BEING ATTACKED, and denounce the peacemakers for lack of patriotism and exposing the country to danger. IT WORKS THE SAME IN ANY COUNTRY." --Hermann Goering, leading Nazi party member, at the Nuremberg War Crime Trials
