I get why pc players laugh at console players fighting over graphics.

Technical advance is the only thing that defines next generation of hardware.

And the tablet controller is such an advance, as was the Wii remote.

Another tempest in a teapot. Graphical fidelity plays a relatively small part in the purchase of this kind of multiplayer-centric game. If I had all three systems, I would still buy the 360 version based on the DLC and most of my friends playing that version. Whether COD on Wii U is the (by a tiny margin) best version in terms of frame rate or resolution is also moot. Based on several other factors, it will not do well, even relatively speaking.

-Controller unproven for these kinds of games.
-Sketchy, unproven online service with awkward voice chat.
-Not a traditional Nintendo-audience game.
-Small number of players online.

However, if the second screen turns out to be a game changer for COD players, things could change. That said, for a fast-paced multiplayer game, I don't see myself looking down at the controller without dying repeatedly.

See the words assets and optimisations in my post above?    Those 2 games you displayed, as well as most all other multiplatform titles back then, were given enhanced assets and optimisations.

Bully on PS2 was released in 2006.  Bully for X360 was released in 2008 with enhancements called Bully: Scholarship Edition.
Alone In The Dark was developed on the X360 and then ported down to the PS2.

We aren't talking about any other games but CoD BO 2.  No title on the Wii U is trying to be a graphical powerhouse.    Most are direct ports (no new assets).   Others are trying to show off the GamePad rather than graphics.   Most mutliplatform titles are being developed on PS3/X360 first and then external development houses are working on porting the games to Wii U.  You're not going to get a better looking game if the assets are the exact same.  To say nothing of the fact that everybody is trying to rush to make a launch deadline rather than having the 3-4 year development cycle that most big PS3/X360 games are getting.

Not to mention 7-8 years of experience with the hardware.

Where exactly have I stated that U isnt next gen?

So you think if a game was build and designed for Wii U from the beginning, the difference would be as big as when comparing PS360 games with PS2? Or that if a game was developed for U and then ported to PS360, the difference would be noticable to be called next gen advance? 

Not as big as the jump from PS2 to PS3.  That was just an insane jump that will not likely ever be repeated.

I do know that a game designed wholly from the ground up on Wii U with the intention of being highly graphical in presentation developed by a team with some years of experience on the system with sufficient budget and resources would defintely stand out graphically above what is seen on PS3/X360.  

Quantifying how much more is where things get difficult.  Not just in simply not knowing the peak potential yet but in the mere fact that "how much better" tends to be subjective to each viewer.

Go back and read that first post you quote me on.   Read if carefully.  Notice the context of what is being said.   Then compare that circumstance to the one I just described above.  It's such a vastly different situation.  Again, they can and eventually will look better.   How much better is unknowna nd may depend on whether developers want to put in the extra work to show it.   Nintendo stated recently that the reason that NSMBU is in 720p rather than 1080p is because it would cost a lot more to develop the game in 1080 yet it wouldn't change the amount of sales at all....so why bother?   If this remains the situation for most developers on Wii U, we may not see many games that really push the system until the PS4/X360 arrive.

- Only a higher resolution has been confirmed, which is likely 720p on Wii U, compared to 880 x 720 on the PS3 / 360 versions. Not a big difference.
-  All console versions have been confirmed to be 60fps, there is no proof that the Wii U version will be more smooth. It likely will be, but even then the difference will be minimal and possibly not even noticable in this case. Even the PS3 and 360 have significant framerate differences.
- The second screen requires very little graphics processing power.

Anyone who claims the Wii U will be weaker than the PS3 or 360 is an idiot, which is probably why I've never seen ANYBODY claim that (Turkish doesn't count).

It's obviously going to look better on the Wii U, but it isn't some kind of spectacular win, in fact I'm disappointed.

Anyway, I promised myself I wasn't going to get this game, but I'm considering it after reading through the OP.
