How do next generation game consoles work?

For two thirds of the competition they work just like the previous
generation. They are not really a new generation, just an evolution.
It would be like calling a teenager the next generation toddler. They
do the same things, but with more power.

The other third is more like works more like a paraplegic with a new
tricked out ride. Everything is the same, but the controls have
changed. This is a "next generation" much more than the others; it is
a true next generation interface, not a self proclaimed next gen box.

As described above, "next generation" game consoles work by generating
a bunch of hype. Basically this means yelling back and forth "I'm
better than you" and generally acting childish. Graphics are only so
much, interface is only so much, neither alone can create a totally
engrossing situation for game play.

That said however, I am inclined to think that this stratagem works.
I want a Wii. However, I also want to play Halo 3. Luckily my
problem is solved by not being able to afford either.

Now, if I lived in a communist state, there would be only one system,
then I would not need to choose. Said system would probably rival the
old Apple 2e for computing power and Super Nintendo for graphics, and
a rock for aesthetics. Oh, and the only game would be tetris. Guess
you can't have it all.
