4 CDs, AND a DVD why?!?!?! (Score 1)

Why are they releasing the game on 4 CDs and a DVD? Wouldn't it make a lot more sense to write everything to a DVD? I remember playing the original game online and being slowed down by my measly 4x CD-ROM. The group would finish a level, decide to go to another level, and at that point it was a race between systems. The fastest CPU/CD-ROM combo would load the new level fastest, and I would wade through the carnage until I caught up to the other adventurers. Is it just me or will adding a disc swap to this just increase the waiting times? I'm not suggesting that a DVD release is the only way to go but, why not put it on there if you are going to distribute a DVD with the set.
