Honestly though, I only notice a real difference when the PC is of very high performance. Most mid range PC's look just like our consoles (to me anyways) so while PC's can look better than consoles most look the same or extremely similar.
I'd hate to have to upgrade my consoles. The whole reason I prefer consoles over PC's is because I know with 100% certainty that when I pop that disc in I'll be able to play the game no matter what. I won't have to fiddle with graphical settings or options, I just sit down and play. I'd rather have the ease of that and the significantly lower price than the graphics a PC can put out. Or maybe Sony can take something from Nintendo's book and bring out something like the Expansion pack the N64 had.
That's my biggest reason for not being a big PC gamer. However I don't see Sony doing an expansion pack like the 64DD or the Sega machines. They tried that route once with the HDD for the PS2 and that didn't work to well for them.
Hmm, very good point, and I can see what you mean. I personally hate that we have to install games. If blu-ray's have 50G why do we have to install a game? That makes no sense, and the nex-gen should eliminate that altogether.
As stated by mjc, it's all about the flow of data. One additional issue w/ the 360 is the storage media. Although the read times for the DVD are faster than the Blu-Ray, the amount of data able to be stored on the disc is about 1/4 (rough estimate) of what Sony has available to it for the BR disc.
Next-gen should follow in the 360's footsteps and allow you to do a full install of every single game you put in the console if you want. I hate long load times and noisy disc drives.
Although this might work for the current gen of systems, you can expect the next-gen games to have 2-5x more data programmed into them which means exceptionally large data packages. If you have to install all of the game, for every game, you are going to need a massive HDD or be constantly shuffling game data to keep your system current with your play library. Look at the current gen issues now with a large part of the 4-5 year owners who are now looking to expand their HDD size for possibly the 2nd time because of memory restrictions. Perhaps once SSD hard drives progress they will become more efficient and able to store more than what is now possible, however, 1T drives are the largest reliable size drives considered by most industry experts.
