So the debate point against is simply that X360/PS3 owners will already buy it on their respective console?

What about Wii U owners that don't have a PS3/X360?
What about Wii U owners that do have a PS3/X360 but want the enhanced experience found on the Wii U version?

What about the fact that Ninja Gaiden 3, Metro :Last Light, Aliens: Colonial Marines, Batman: Arkham City, Battlefield 3, Darksiders II and others are also in development by 3rd parties? Are you just going to claim that 3rd parties shouldn't bother because they are already coming/on the PS3/X360?

What about the easy ROI factor? 250k units would likely cover the porting costs. Anything above breaking even is cost amortization which every developer would love to do.

Me personally don't argue AGAINST porting games to WiiU - even if it sounds like it at times. I'm merely trying to see it from the developers point of view. I'm just not sure if there will be a big enough number of sold WiiU's out there that's also's gonna buy GTA5.

The more games they port to WiiU the happier I am! Out of all those u named I'm just excited about Batman for now, but I wanna see massive 3rd party support for WiiU - and that means GTA as well, but I'm not too sure Rock* is going to port it...

Rockstar not Rockband.

The gap between the two games (even with the DS version launching 7 months prior and on a system that had what 2-3x the userbase) is within 250k.  I wouldnt be ringing the bell on making that my core arguement to have a Wii U version. 

It definitely destroys the R* can't sell games on Nintendo consoles argument.

VIPER!!!! You're BACK! :D   (this is padib by the way)

I think your wrong on not admitting the entire tablet craze that is going on throughout the world.  I believe if marketed right Nintendo can ride to the top with the help of having a tablet like controller able to do many things that a basic controller can't do.  At first I was like bleh... that might be alright when I was first exposed to it.  I am decently impressed after watching a few Nintendo demo videos on what they are thinking of implementing for the controller.  I see the future and the future is Nintendo on top again.

When the DS launched touch controls were labeled as fad (now you have almost all phones being touch phones).  When the Wii launced motions controls were labeled as a fad (now you have all 3 with motion controls).  Tablets are already a fad before the Wii U launches so how can you not say it won't be a success if marketed right, has a good price point, and great games. 

I know you are talking about Nintendo fans buying GTV for a Nintendo system.  I am just stating that the Wii U will have a large install base.  It might not top the Wii but it won't be like PS2 - PS3.  I had to use someone's quote to go off on a rant about why their next system will actually sell and that third parties need to get their heads out of their asses.

Well, if Super Mario Galaxy selling ten million copies isn't doing gangbusters, then I guess core games don't sell well on any system.

But all kidding aside, the term you are looking for is probably "hardcore" (defined as everything that is normally not associated with a Nintendo system) or more specifically "dudebro games".

Danne, I find your best point here is this, and you bring up a good one:

But the question can be asked in return. Did Activision lose prestige in its COD brands by porting it to the Wii. Mmmm, I would say no. Did they make money? Hell yes.

I think it follows pretty much the same pattern here. Matter of fact, COD on Wii actually sold better from launch to now. Shows how much of the potential market was hogged away from Nintendo, but that's N's fault I'll be the first to admit. It's their fault to have omitted at least basic HD graphics on their Wii, but that's subject for another debate. In the meantime, Danne, here are the COD sales on Wii you'll find them very interesting:

It actually goes down EXACTLY release upon release. Sad, but surprisingly true, despite the Wii's userbase going as follows:

Despite the COD growing and breaking records year over year. These numbers prove the power of:

Time (legs)

Marketing (Microsoft and Sony focused, though more MS)

Word of mouth

Consumer satisfaction (or possibly in this case dissatisfaction, and preference of competitor offerings)
