Not having a clue is where you are at.  It has been clear in my OP and comments that I too thought that changing the GPU would not have been an option. 

Either way, losing 50 million up front because of a design change whatever that may have been would be peanuts if you sell 40-50 million less consoles throughout a generation.

No, the losses would be far bigger than 50mi up front.

Sony alone lost more than 3bi with PS3 problems and Microsoft face a similar figure with RROD. Consoles are not easy or cheap things to build, or why do you think there are only 3 major manufacture on the market?

Without competition PS4 could sell way more than 15mi this year (if the price was the same). How could Xbox division would justify investiment 4 major studios building AAA games for a whole year, also the exclusive contrats for Titanfall, Ryse, Dead Rising, Quantun Break and  others?

Of course the XOne was rushed, of course there are things missing, but the 2013 release was the target date as far back as early 2011.

I agree that the number could be much larger than 50 million.  Or, it could be 10 million.  Neither of us have any real idea what it would cost to change only one aspect of a system and delay it's launch 6-12 months.  It doesn't increase the costs to advertsie or even software development costs, as they were costs that would be spent either way.  The cost impact have more to do with contract obligations to suppliers of parts. 

As far as the 15 million lead?  Maybe or maybe not.  Maybe a bunch of the buyers would sit on the fence waiting for the final reveal of the XB1 specs, mayb not.  All of this is speculation and can't be definitive as you seem to imply.  Especially when it comes to release dates...
