plz explain how

From what Phil Spencer said recently in an interview is that bundles are usually worked on almost a year in advance.  It isnt something they just put together. So my guess would be that Sony is the same way.

However there is rare instances i believe they can slap a quick bundle/promition together like Microsoft did with Xbox + one free game during the launch of destiny.  THat however isnt a designed bundle but more of a promotion.

MS won't win in NA with a $50 cheaper price, also no Company on this planet do something to make you happy and lose money.

MS are just wasting money to save thier face in NA, and this is not good.  I know X fans feel better if PS4 does not crush XOne in NA for at least one month per year, but everybody should consider the fact XBox should make a profit, and selling better for a couple of weeks because of price-cut after a price cut is not a victory, but a defeat.  if you need to do all this to sell better for a couple of weeks in your own territory, it means you have A PROBLEM, A BIG PROBLEM.

This.

Sony are watching MS from the above, they can play their cards whenever they want.  Many here look at the micro micro vision(2 days, 1 week, 1 month), but you have to look at the macro vision, and MS now is the one with the water in the throat, playing all their cards.

technically XB1 is $100 cheaper than ps4 right? I see the Unity/Sunset bundles selling for $350 vs $450 for Destiny ps4 bundles.

MS is definitely throwing cash to get some XB1 sold, but the thing is, I think PS4 will still outsell XB1 for November and beyond. History is telling me, once you take a big lead in the console race, it is hard to fall behind.

A price cut causes a spike, how is this surprising? Some posters are getting way ahead of themselves.

No more surprising than a bundle with a hyped game causing a spike, but that was also hailed as the second coming in March.  I won't be at all surprised if these bundles drop off the top sellers without ever reaching the top 100 annual lists. 

This has been a long stanbding offer, so this isn;t really much of a factor. People could have got a Xb one for $300 this way for the last several months, but it didn't stop PS4 from winning every single month up to now, including October (I have no doubt).

We are less than a week into a $50 price cut (Xb one's first genuine price cut) and a number of very attractive bundles. Why is anyone surprised, or much less worried, by what's happening?

There is no point in Sony reacting until they see what the longer term effect of the price cut is. And Sony only has so much adveertising money, so they need to time their advertising of bundles so that they have peak awareness when the bundles actually come out. Another week or so I think.

Yeah, this is way out of hand.  Where did this attitude go?

And that attitude continued on for two weeks of the product in question sitting at the top 10, most of the time at the top 5. 

And now suddenly, being in the top 15 for less than a week is cause for mass hysteria? 

Given the current situation, Sony has excellent sales but need money and MS has poor sales but plenty of money. That's why.
