not really agreeing with many points in this article. Gamecube medium was 1.5 GB while PS2 had 9GB of space max, even though its disks typically came in around 4 GB. It was obvious that the graphics were comparable in some cases and in others GC was the obvious winner due to some graphical capabilities built into the system. After all, it's not like we're talking the difference between a PS1 disc and an N64 cart. Even in N64's early titles, the lack of texture data was obvious. This isn't the case with 360's titles, which have a very crisp and detailed appearance.
N64 Cart (avg 8MB) versus PS1 CD (650-700MB)
360 Disc (9GB) versus PS3 BD Disc (15-30-50GB)
9GB is more than enough space for game data. What will end up taking more space ultimately than textures is the use of video, which can be compressed to an MPEG-4 variant that the 360 processors are more than capable of handling. In the end, if it all comes down to switching discs (which seems unlikely), I think I can deal with having to get up and swap the disc a couple of times.
I do think that PS3 will win, namely because they've given consumers what they want (and probably a few things they don't need) even if the price seems steep.
The brand name loyalty carried over from PS1 to PS2 was enough to kill off Dreamcast despite the innovative titles Sega put out. Everyone was willing to wait for PS2. I think the same thing has pretty much happened with the PS3, but MS has the money invested to stick around, unlike Sega. It will be interesting to see what happens. I think people are letting the quirkiness of Nintendo's product distract them from the fact that diehard gamers, who have also become consumer elctronics buffs, are going to want their products to contain all the bells and whistles, HD res., HD content playback, Dolby Digital, and a multitude of buttons. I think Nintendo's approach is unique, but not necessarily lasting. Hearing that its AV output is not much better than a souped-up Xbox (minus the Dolby digital), I'm skeptical about spending $250+ on outdated graphics and sound for my LCD and surround system.
