That's debatable ... 

With this year being very likely the peak for the WII U, I'm surprised that the WII U will go on to sell similar numbers like last year. With the WII U currently tallying up to 2 million units with latest shipment data suggesting an overtrack of 300K units, the WII U has so far sold 1.7 million units this year. If we can take a look at an otpimistic case that the WII U will sale about 50% of it's units for the holdiays that will come to around a total of 3.5 million units which is roughly a 10% increase from last year's sales of 3.2 million units. 

At the end of the year the WII U should come to have sold 8.8 million units and the next year is the WII U's only decent year left since Nintendo will have played every cards they can get their hands on. With another optimistic expectation the WII U should reach 11 million units by then but how exactly is Nintendo supposed to sell 3 million more units when the wells are dried up ? 

Wii U still has price drops, Zelda, and the long term legs of Smash and MK8 ahead of it. It's not just going to fall off the earth next year, it will continue selling.

Yes, I know that the WII U can still do price drops but that won't make the system more enticing to purchase ... 

Price drops really only work when the system has tons of momentum to rely on and if consumers find the platform unattractive at $300 then what difference will $200 make ? 

The sales boost from MK8 is wearing off and the same is bound to happen with Smash. As for Zelda, I'm wary on that one cause of art style issues ... 

I don't expect the WII U to fall off the cliff next year but I am expecting a decline yet as for 2016 I don't see much of a future for the WII U or a lack thereof a future ...

Wii U hardware still hasn't returned to its pre-MK8 baseline after 20 weeks, despite a three month game drought. This game and Smash will make it well positioned as a family/secondary console, but $299 is too much to ask of either of those audiences, so a lower price will help. That's how I see it, anyway.

It could. I'm not saying it will... but it could. It's a small chance... but it's still a chance.
