When I bought my wiiu I could decide:
298€ zombi u deluxe bundle
249€ for the premium
198€ for the basic model
I took the basic model with monster hunter and paid less for what i had to pay for my wii back on release day.
So looking at those prices the wiiu already had an inofficial 100€ pricecut here in germany.
I doubt the official pricecut will be more then the inofficial or at best match the inofficial pricecut at e3.
If they decide to pricecut ... depends on the price of the other two consoles.
edit:
maybe a 3d mario(+kart) will arrive before e3 and with zelda the sales might skyrocket for the wiiu so that nintendo wont see a neccessary to pricecut.
and when the console starts selling pretty well the inofficial pricecut will get droped.
So if you want a wiiu in the near future buy it now. it wont be cheaper then it is now for a long while ...
and if they decide to pricecut have fun with your ambasoder games while still not having paid more then the official pricecut :p
