No. Maybe the odd person here or there, but nothing major or even notable.

Oh, it's much bigger than that. I think the PS4 and Xbone will be canceled altogether now.

People who wants a PS4 or XB1 already have 400/500 dollars in their wallet for their console of choice.

Why would a price cut from 350 to 300 dollars change anything, as they already rejected the wii u despite being cheaper ?

There would be cancellation if XB1 was going 400 dollars for example, but wii u price cut will not change anything for PS4 and X1 preorders.

oh, pezus!

I already own a Wii U, but I don't see why I would cancel a pre-order, its basically a lay away and lets us pay it down over time before release. I am certainly not canceling my PS4 pre-order, though that Wind Waker gamepad has me thinking if only my Wii U purchases were strictly account based by now... Anyway, no, it should not, unless you pre-ordered an XBone, in which case, bad move on your part.

Is this a serious thread?

I think it's a fair question, but it really depends on who the buyer is. If we're talking about early adopters that are really just interested in Sony/MS products, then no.

If we're talking about early adopters who are just rich families and were going for a family console but were not convinced in the WiiU and went for the other two instead, this could sway them. Yes, rich people also compare prices. I know, I was raised in a rich family.

No.

Although, I have to say, that bundle is by far the most tempting thing I've seen yet from the Wii U camp. I'd love to have it, if I had the money to spare.

No, people won't cancel pre-orders. But, why aren't Nintendo making a bigger deal out of the price cut (it's worldwide cut, isn't it?). I had no idea it was made cheaper.

While someone out there will, the pre-orders are by the biggest XB/PS fans and they'll still get it even if the price cuts finally convinces them to get a WiiU as well.
