There would be a higher mem requirement. The way these transitions work is by using 2 sets of volumes, each one loading different sets of data. The world you transitioned from isnt completely dumped. This is why it couldnt be done on the ps3, it just didnt have the mem required. Also btw, transitions wouldnt be toggled, this would be a fundamental change that would require input from every dept. Someone like Yoshi P would need to sell the idea to higher ups, and im not sure they would give it the stamp of approval as it wouldn't necessarily create more retention. However, i do have faith that this is being worked on, just a gut feeling.
