how much did mario kart sell on wii, ds and 3ds, again?

Look at the Wii, DS, and 3DS hardware sales. Now look at the WiiU's hardware sales. There you go. 

How much did those consoles sell compared to the Gamecube again? 

Not enough to move the Wii U hardware obviously

I couldnt give a shit when PS4 passes Wii U , im just glad Wii U is selling better and hopefully has a better 2014. I just hope Wii U has a better first half of the year than it did the last.

Oh right I forgot Nintendo consoles are Mario Kart machines now and there are millions and millions of people waiting for MK to be released.

Come on we all know its going to give the Wii U a great boost in sales (all first party will) but it can't carry it all gen.

I don't doubt PS4 will pass WiiU this year. But for your bold prediction to come true, WiiU will have to sell close to zero units in Q1. I simply can't see that happening. If I'm not mistaken Sony's own predictions suggests PS4 will stand at 5-5,5 million by the end of Q1, that's a figure WiiU will most likely reach by the end of January or early February even with conservative estimates.

I'd say with the most optimistic estimates for PS4 and the most pessimistic estimates for WiiU, PS4 still won't pass WiiU until May at the absolute earliest. A more realistic time frame is July. However, if Mario Kart 8 will be released in early Q2 I think we will have a somewhat different scenario, with PS4 passing WiiU in September/October at the earliest.

Highly unlikely. The lowest they'll drop it is $50, to $249, which is the price the Wii launched at. Any lower and  they'll start losing a lot of money.

Of course, it won't help too much, as price isn't the Wii U's problem. It's already $100 cheaper than the nearest competition, and only $50 more than the Wii was. No, like I said above, the Wii U' s problem is that it isn't as appealing to the core gamers that are still around after many of the casuals left. Though, it will probably see some success in Japan.

You obviously didn't read what I wrote. The PS4 is already most likely already over 3.5 million in sales now and PS4's still have backed up demand WW especially at Gamestop in two months time. By the time that demand is finished we're looking at 5.5-6 million which would be around the beginning or end of march. The Wii U will go into low season as it usually does in january and it will not be able to combat the with the PS4 once it launches in Japan in February further bolstering my point that an extra million will solely come from Japan in the first week of launch. There will be no millions coming to Nintendo within such a short period of time. The demand is not as high as the PS4's not at its launch and it will not continue to have as much. 

The Xbox One is the console that fits the description of the scenario you are creating. The Xbox One will surpass the Wii U by the beginning or end of Summer. 

Lets make a wager.

If I win and the PS4 passes the Wii U by the end of first quarter I you have to put on your sig that my theory right.

If your theory is true, then i will put up a sig saying that what you are saying is true.

As I said before in my earlier posts, I don't know whether it is a blessing or a curse that I have a alarmingly close prediction to Michael Pachter about the Wii U's lifetime sales and window of being passed by the PS4. The PS4 is going to pass the Wii U with ease. A years worth of the Wii U's sales overthrown in four to five months.

PS4 will outsell it June-September, and X1 sometime next year.
