My problem with disk switching on consoles is it's all going to depend on the game. An RPG with like 40 hours of gameplay isn't going to be that bad for 3-4 disks. So you can just guess that there would be like 10 hours of content on each disk. However, I think back to a game like Metal Gear Solid on the PSOne for example. Say around half way through or so there is a disk switch and the game is about 4-6 hours (probably half that if you know what you're doing).
For the heck of it, lets swap the positions of Gears of War and Blue Dragon and say that Gears of War was a 3 disk game. So around 8 hours of gameplay on 3 disks? Ehhh, I don't know how excited I am about that.
Minus the possibility of damaging one of the disks of your 3-4 disk set (my FFVII barley if at all works through anymore) and being out of an experience till you can replace it, I'd rather not have the smaller games ending up on multiple disks if future games do infact take up all that space.
Now when it comes to PC games, I hate switching disks, even if I have to do it the one time for installation. Trying to sort through 4-5 disk installation is just a chore.
