With the current library? Below 100 for sure.

Even though I already bought a Wii U I think the 300 dollar price tag is too high, which is why I decided to buy mine at target when they were offering a 50 dollar gift card with a purchase of a Wii U. So basically I bought mine at 250 which should be the set price imo. I think a 50-100 dollar price drop would help the wii u but not save it.

I'll buy it when the games I want are out.

Perhaps if Nintendo provided integral reasons that warrant a purchase other than, "Please wait, there's more coming; we promise."
I feel Nintendo's noncompetitive nature works against them in certain cases especially marketing to those in the red ocean.

I was originally gonna wait until they bundled a different game (like Pikmin 3, or MK8) or dropped the price by $50. Thankfully both of these essentially happened, not entirely from Nintendo but through retailer deals aswell. Target had a $50 giftcard with Wii U deal, which'll essentially net me MK8 for free, which'll also get me Pikmin 3 for free. I was also exempt from paying tax thanks to the Red Card, and the money I saved from that netted me The Wonderful 101 which was on clearence at ToysRus for $12. Net total for all of this still comes out to just above the normal price of a Wii U plus tax at $320, but you have to keep in mind the value here! If we count those 4 free games, it's basically like I bought the Wii U for $100!

ps4 - 400
xb1 - 300
wii u - 200

that's how i look at it.

Price is fine, at this point it boils down to Software. Once X or Zelda is out i'll purchase one.

Very true I would imagine. I don't really have any clue what the actual production cost of the Wii U is today, but since it's selling quite few that will also push up the production costs, even if their hardware is weaker and therefor cheaper than the cometition. So I imagine you are very spot on there.

They could perhaps lower it to $200, if they knew the console would explode and sell at massive numbers, thus bringing the production cost down. But I don't think it would sell that well. :( So a $100 price cut would not work if favour to Nintendo, and a $150 price cut suggested by me would absolutely piss off investors.

And Nintendo doesn't really have any significant hardware that they can remove from the console to sell a "budget" version either, like MS could do with X1 if they really wanted. They could remove the Kinect. The Wii U is already gimped enough.

I don't think there's really any other way than to sell the console at a loss, more so bigger than smaller, to actually increase the numbers as much as I want it to sell.

If Nintendo manages to sell 50+ million this generation I am very pleased, but, I do have some serious doubts they will. 30+ will be okay, but lower than that I will actually feel sad. 

I'd buy a 2nd Wii U at the current price if Nintendo copied Google's single account system and allowed me to share digitally purchased games/NNID across machines.
