I would rather define it as gameplay that's so revolutionairy and fitting with the given platform, that it defines either the generation or the console the software was on. Pong did it, Donkey Kong did it, Super Mario Bros. did it, Super Mario 64 did it, Ocarina of Time did it, Goldeneye 007 did it, GTA III did it, Halo perhaps did it, maybe even Metroid Prime and RE4 did it, Wiisports did it, Wiifit did it... many games have done ''next-gen'' gameplay, although the term next-gen is somewhat silly.

Correction: No more Head-Tracking in Boom Blox!

Although I haven't played it (yet), I'd think that PES 2008 Wii offers a "next-gen" gameplay experience that quite frankly couldn't have been done with the previous consoles.

If you can't find new gameplay, you just aren't looking.

Xbox Live on Xbox offered the online portion you just mentioned last generation.

Better framerates?  No.  That will never be a next gen feature.  Frame rates are a balancing act developers will always fight with.   For example, we've had 60 fps games since the N64/PS1 days yet not even half the PS3 games run at 60 fps.  Ironically, more Wii titles run at 60 fps than PS3 titles but as I mentioned, this is not exactly realtive to raw horsepower.

Difference between what MS offered online last gen and what they offer this gen is substantial. ps360 don't always offer next gen gameplay but games can be found where this is true.

Here are a few things that I found "next gen" on the 360...

In Ikaruga (old game) you can go and save replays and then people can download your replays. I downloaded the replay of the best ranked player on xbox live and he gave 300 ideas on how to fight bosses and such...this I find very next gen as it eliminated the need for guides.

More people online. Halo 3 has 4 player co-op mode where you can play the campaign. Frontlines:fuel of war has 50 player online death match mode. This was not possible before and is hella fun.

Rock Band - everything about the game is next gen.

Also there is the case of AI and game environments. Things are more destructible these days than before and that plays part of the gameplay. Enemy AI tends to be a lot smarter in some games which ads depth to playing the game. Playing on very hard these days is no longer an impossible task of sheer luck.

Online - downloading demos, game movies, podcasts, songs, movies. All this was not possible before 2005 on any network(legally)...let alon on a console.

To be honest, I don't find Wii to be next gen at all. I mean, controls can be inventive(sometimes) but once you get used to them(usually within the first hour of playing the game) its back to playing the same old Zelda and same old last gen ports and upgraded sequels. I would call wii sports next gen...but since then all the games like that have just copied wii-sports and all the normal games have really added nothing new gameplay wise. If you think shaking the wii more is next gen...power to you.

So wii - not next gen(gameplay or visuals)

ps360 - next gen visuals, sometimes next gen gameplay.

Winner - ps360 :)

No current consoles do not provide a next generation game play experience.
BTW: Wii motion control is not innovative. The PC mouse uses motion control. point and click

Rock on 2008, weren't you banned?  A mouse isn't motion controls.  By that logic, an analog stick and pushing buttons is motion control too.   Man, you didn't learn anythign from that ban at all, did you?

Played MP3 for about 8 hours, got bored before I finished it tho. Great game control wise but threads way too much of the familiar ground that the prequels established...look and gameplay wise...  Again, controls work great but once you are used to them, its part of your routine and you're sitting there playing a game that is very similar to metroid prime 1 and 2.

Ima rent godfather one of these days...its rare as the place i rent it from doesn't have it.

Isn't the point of play control to lose yourself in the control and not think about controlling it?
