No current games need 50Gb+ of space because the option was never there. But already games like Lair are taking advantage of the increased disc space.. A single level of Lair can take up to 7-8Gb's of space. Could you imagine what Bethesda (Oblivion) and others can do with this increased space?
Of course you can't tell the difference between a standard DVD and a HD one. It's new format. What format ever created used it's full potential at the beginning? I cannot say for certain that a HD format will look dramatically better than the Standard format but the possibility is there.
Yes I believe the developers will be using most to all of the PS3's potential sooner or later, What console hasn't? I think you give the developers (well certain ones
) less credit than they deserve. The introduction of multi-core processors is a good thing. By the end of the Ps3's life we will probably have more processor cores in our computers.
I think you have to think of what you're getting for $600 rather then what else you could do with $600. You are getting a gaming system that never need to be upgraded (larger HDD's put aside), That will Play every game out for it with no problem, And with graphics that
will rival a PC's.
The large price tag aside, you can't measure a console on it's hardware alone, software is the biggest factor. Right now the Software side is not ideal, but with time we will see titles such as Ratchet and Clank, Final Fantasy, Jak and Daxter, Kingdom Hearts, MGS (of course), Not to mention some of the less well none titles.
I'm done ranting
all I've got to say now is that if the technologies listed above will help to further the games to be released on the PS3, many of which i Love, then It's ok in my book. The industry must push the envelope, even if that means a couple of dead-end products.
