I hope so. I won't pay more than 200€ for the thing, specially when rumours of the new system coming in 2016-2017 (even if it's a handheld).

They will,it's inevitable(Especially if the successor is near,although for me is winter 2017,i.e not so near but I can see the announcement of it in E3 2016 because there is a trend,dolpin(gc) tease 1999,announcement E3 2000,release in the holidays 2001,revolution(wii) tease 2004,announcement E3 2005,release in the holidays 2006,NX if it's a home console of course,tease was in 2015,announcement E3 2016 ?,release in the holidays 2017?)...
It's wii u's third year,gc got two,one in 2002 and another one in 2003 and they were big with a great effect,especially in the USA...

Do you want any prediction?May 7th,Fiscal year 14 results announcement!It had  been said the nintendo wouldn't do a price drop before the end of the fiscal year...
The situation is ambiguous though,Iwata was recently showed that they don't rule out the possibility but someday with some statements of his I got that nintendo is very reluctant to do a price cut...(He had said that is about the games and not the price or what they do with 3DS wouldn't work with wii u or something like these,I love iwata but this aspects exasperated me,price cuts always Ehave way greater effect than game releases!)

Edit: I'm seeing a 50$ drop and I want another 50$ in 2016..Like gc had in 2002 & 2003

I say it will get one this year

Well... Valuable sounded better in my head! Thanks for the correction

September-$249.99 Mario Maker bundle

I'm willing to bet on it

If they would cut prices, it would be $249.99. I'm guessing thats as low as it'll get, at least for a while. But yeah, they should cut the price, just to help push Wii Us and the games coming out for it.

Maybe during E3, if not, hopefully around the end of this year.

To be fair, I was a bit pedantic. Demand curves come from the sum of all consumers' "wilingness to pay" which derives from how much they value the object. But it is still useful to distinguish the difference, because different target consumer bases can have different values, therefore different willingness to pay, and therefore different demand curves, meaning a marginal change in price can mean a more or less differential change in demand. Nintendo mustn't evaluate whether they should do a price-cut solely based on whether or not XBO gets a pricecut to the same price, because the demographics Nintendo targets aren't exactly the same demographics XBO targets. 

They have to, otherwise it will confirm my theory that they already gave up.

I'm in agreement with you. Near the end of the year, although I would push it back to October or November even to try to catch the beginning of the holiday shopping for incentive. Likely the $250 range. It does partly depend on how the exchange rates are though.
