The next generation of consoles, possibly underwhelming?

I've been recently thinking about what people might be doing with this next console jump, and I'm not sure there's going to be a huge change.

If we look back on past generations, it's always been every other generation of consoles that made a big leap.

Let's take a look back:

- Going from Xbox to 360, or PS2 or PS3, huge leaps with internet pervasiveness, downloadable games, menu & interface. Even going from Gamecube to Wii, huge controller change, the advent of motion gaming was a huge change, weather you like it or not.

- Going from PS1 to PS2 or N64 to Gamecube, let's even say Dreamcast to Xbox. Sure the graphics were better, but not much else changed. Games were pretty similar, and expectations for games were similar.

- Going from SNES to N64, or Genesis to Saturn, HUGE leap, and with the PS1 coming out and the advent of polygonal gaming, things were changing about games in a big way.

- However, going one generation back, NES to SNES or Master System to Genesis, Not much really changed... it was mostly just better graphics.

I might be over-explaining something fairly basic here. It's really just your basic tick-tock theory, but it's good to take a look at the past...

Even sight-unseen, my hypothesis is that the next generation of consoles will simply give us better graphics and not all that more advanced games or systems. What do you guys think?
