Ummm, the original post in this tread said they would like to see the PS3 with the Blu-Ray player optional. That's what started me as saying I didn't think optional hardware would be the way to go.
Now, I didn't know the HD-DVD drive couldn't be used for games. I wonder if developers are going to need the extra space that HD-DVD and Blu-Ray provide. Will this finally be something to differentiate the two machines, with the PS3 getting the larger, more immersive worlds, or perhaps just a lot of extras with the game to help fill the extra space.
