So, if were to apply this to the Wii U mario pack , the Wii U sales for 200 euros or dollars. The Wii U is saved!

Not... really convincing logic, is it?

SO the xbox1 is only cheaper for the first month you own it. :D

Except the difference being that the PS4 and XBO were neck and neck in February NPD. There was some actual competition there. I'm not sure how WiiU applies with it's 82k in sales. 

PS4 is $450 in Canada so IF your interested in Titanfall its $60 cheaper here.

I mean you would still have to buy a play and charge kit for the Xbox one if I'm not mistaken. On top of Xbox live being $10 more expensive overall I would have to say no.

Or they could already be paid up and switching over :D

Edit-plus that free month

They might as well make it official and lower the console alone to $399.

It will make it sell a lot for sure, but I still don´t know if it will sell more than the PS4, after all, PSPLUS gives 5-9 free games for the new Ps4 owner, namely, the ones I have got last week when I bought mine:
1 - Don´t starve,
2 - Rezogun,
3 - DC Universe,
4 - Blacklight,
5- Outlast,
6 - Warframe,
7 - Zen Pinball.
Some people got contrast too for free.
That said, as a Xbox One owner myself, it makes me happy to see the install base increase, since it can lead to cool exclusive games.
But, overall, the PS4 is still the better deal.

Where are all these price drops coming from? In my country the PS4 has had a $50 price drop in certain places while the X1 has remand the same price.

Yes and last gen Xbox had the advantage the WHOLE gen on price and even had a $200 advantage at the start. It still got outsold even with a significant head start. So obviously a bundle isn't going to help turn this strong PS4 position around.
