Yeah,

1. Nevermind my Mass Effect statement, though I really don't lump that game with FPS's.
   
2. Deus Ex isn't doing new things, it did new things 7 years ago.
3. System Shock-- same as above but add, what, 10 years?
4. Rage? We've only seen a short trailer for the game and so far there's nothing really evolutionary about it. If you think it's revolutionary because it's pretty, then you might as well call Doom 3 revolutionary along Resistance: Fall of Man.
5. Halo 3 hasn't promised to do much new other than 4 player co-op (unless I completely missed something). 4 player co-op isn't really anything revolutionary, it's just kind of the next logical step.

Thanks for setting me straight.  I see the error in my logic now.  By the way, since everyone that is anticipating MGS4 for the PS3 has already bought one does that mean MGS4 won't be a system seller?  I mean, after all, all the PS2 owners that love the original MGS series have more than likely already bought their PS3 in anticipation of the glory that will be MGS4.

Have a nice day. 

Well we will just have to wait and see who will eat humble pie. Halo 3 will give a small sales spike to 360 then back to average sales is my prediction.

Nintendo's big 3 will sell more consoles than halo 3 will.

have a nice day too

Bioshock pushes FPS because it's pushing AI and gameplay in a FPS in a new direction.  Metroid Prime is getting credit solely based on it's new control scheme, which since other games on the Wii already were using motion controls does it really add anything new at all or deserve to be in the same sentence as Bioshock when it comes to adding something new to the genre?

Indeed we will.

We've gone way off topic but... Nintendo has nothing to do with this argument -- why did you bring that up?  Please answer my question concerning MGS4 as to whether or not it will be a system seller.

 I think it will sell consoles.  And I am a Wii fan mostly.  Don't just walk into threads and post negative stuff like this.  There is no reason to mention Nin's big three in a thread called "Any 360 owners NOT buying Halo 3?".

I am telling you this because your low post count might mean you are new to boards.  When people are talking about things like actually buying or not buying a game that isn't the place to post stuff about humble pie or other game being better, on another console, that come out in different months, from a different genre.

An on VG charts we say Eat Crow. 

So because Metroid Prime is pushing new controls in a completely different way than all the Wii games it gets discounted because other Wii games use motion controls?

That's like saying Halo doesn't matter because all the console FPS games before that used a controller. 

Halo was the first console game to allow people to system-link and play up to 16 players.  Halo 2 was the first real online FPS for consoles.  Metroid Prime on the other hand doesn't appear to actually add anything new besides using motion controls which have been used in past Wii games (maybe not as well implemented, but still used).  Do PC games get labelled revolutionary if they improve the mouse and keyboard control scheme slightly compared to previous games?

But MP isn't a slight improvement, that's the thing. If it was just Metroid Prime 3: Now with same Gamecube controls then it wouldn't be anything special. Instead, it's Metriod Prime 3: With brand new Wii controls that worked wonderfully and one that nobody has ever done before so yes, the game is special.

As for Halo, it was special for two reasons 1) like you said, the system link ans 2) because it revolutionized the way FPS console games played. If a PC game did something that made a complete new way of playing due to its controls, then yes, it would get recognized. Metroid Prime isn't just slightly improving the controls at all, it's making a brand new control scheme that just works really well. A game that just slightly improved the control scheme would be something like RE4: Wii Edition therefore not special in a revolutionary sense (though special in that it made that game better).

"Please answer my question concerning MGS4 as to whether or not it will be a system seller. "
same prediction as halo 3, These games will boost sales slightly for bit and that will be it. Sequels just dont sell systems like they once did.
I brang up Nintendo's big titles as comparision.
