Gran Turismo 7, GT6 will be released on PS3.

Let me spell wii u situation for you: it's a new videogame that haven't received it's system sellers yet, it's current sales are irrelevant so come talk after the big hitters come.

And you seriously dare to ask "why would the holydays change anything"? I don't know, maybe mario 3d, mario kart, smash bros, SMT X FE, bayonetta 2, wonderfull 101, yoshi yarn, monolith X, retro project, watch dogs, batman, AC 4 + whatever unanounceds titles there are. most of those games should be released by this year's end, with some being left for 2014. 

Oh my, a new console competing with cheaper previous generation consoles that have a bigger library, I think that's the first time in history that happens. If that was a reason for a console to fail then NES would have been the last sucessfull console in the world.

bolded 1: if you think third party's won't port 8th generation games to wii u (if it doesn't become the leading platform) you are delusional. companys like money, a wii u port will give them more money, it's pretty simple.

bolded 2: wii u isn't much weaker than their future competitors and your will isn't gonna change that unless you develop curé syndrome. a gamer who buys a console for multiplatform will get the cheaper console with the best exclusives, a.k.a wii u. In case you didn't notice, when someone plays a videogame there isn't a magical screen that makes a side by side comparison with other consoles so you can see wich has 10 more pixels. As you stated, these people want the multiplatforms so any console that has them is an option and wii u is the cheapest one.

We will see if it makes a big difference. All we know is that the iconic Nintendo franchises alone weren't enough to save the N64 and Gamecube. I also doubt people will care for watered down ports of games like Watch Dogs. Everyone and their grandmother is excited about that game, but keep in mind we have only seen it running on a high-end pc and ps4. The Wii-U, ps3 and 360 will probably look like garbage in comparison to the next gen / pc versions. 

I'm done discussing this, if you really think people who play games like Call of Duty, GTA, Fifa, Assasins creed etc. will pick the Wii-U as their primary system you're living in another dimention. Wii-U doesn't even ship with a descent controller for those games(and no people are not going to hold a big clumsy tablet controller to frag in COD). 5-6 times more powerfull makes all the difference in the world, not just to gamers but to developers aswell.

People will buy a Wii-U if Nintendo's franchises are the most important to them, if not they will pick PS4 or nextxbox.

and we go back to the controller excuse again. right, because a controler with 2 analogues, + pad, abxy buttons, l,r,zl,zr that holds and plays like tradicional controlers is certainly a challenge to use. 

ps4 and nextbox MIGHT be 5-6 times more powerfull than their predecessors, wich means they're only marginally more powerfull than wii u.

It IS 5-6 times as powerfull in computing power, it also has 4 times the memory at much higher speeds. And that really isn't a marginal difference, anything under 100% difference is marginall. The biggest difference being that Wii-U won't be able to do physics like PS4 and nextbox can, therefore if these become an important part of the gameplay Wii-U can't run those games.

But there's no use in arguing about this anymore, i'm just afraid people might make a wrong decision in purchasing the Wii-U for the wrong reasons.

A friend of mine was thinking about buying one because he wanted to play some of the motion controll games from the Wii again and thought that if he bought a Wii-U he would be settled for the next 5 years getting all the same games exactly the same way as he would on a PS4. He wasn't informed about any technical aspects just like you mentioned most people aren't.

When i told him that the PS4 is going to be much more advanced and that Nintendo isn't well known for the best third party support(i said ''getting games like GTA and COD) he was suprised. He ended up buying an discounted Wii instead and is now saving for the new Xbox(yeah his fellow students play xbox, so no PS4).

The thing is if you're not really interested in Nintendo's own games there is no reason to buy a Wii-U and you're going to get the better experience on a PS4 and Nxbox for the other games, if they are even released for Wii-U.

are you blind? i said they might be 5-6 times more powerfull than THE PS3 AND XBOX 360. THE WII U IS LIKE 3-4 TIMES THOSE CONSOLES, THUS MAKING THE DIFFERENCE BETWEEN WII U AND PS4/NEXTBOX ONLY MARGINAL.

IF someone isn't interested in sony/microsoft own games, wii u is just as good as an option, if not better.

I see that you're new to these forums and it shows because you're acting like a clown in my opinion. Go do some searching before screaming things you know nothing about, not one thing you just stated is true.
