Unless the Kinect is discarded and the price bought to around 100 lesser than PS4, I don't see it happening either.

Truth be told, the PS2 dominated because it was out first, had a huge install base, huge library of games and the lead platform for developers.  All of those pieces is what made the PS2 the console to get even though it was the weaker console.  Since the PS4 and X1 are launch at the same time, the X1 does not have none of the benefits the PS2 had during its run.

Anything can happen during the run the PS4 and X1 will have in their lifespan.  MS would need for Sony to make some serious blunders like MS did during the 360 era.  A RROD/YLOD situation would be on that type of order for the X1 to gain ground.  Having a slew of big AAA games that actually sell like Halo would be another.  Either way, it will be a huge effort for the X1 to overtake the PS4 simply because Sony has a better presence around the world than the xbox brand.

Totally agree with this statement.  The X1 can be totally successful without actually selling the most hardware.  I am sure at the end of the day, MS is more concerned that they have a successful profitable product then selling the most hardware.  I am also sure that even though Sony sold a hell of a lot of PS3s, its not going down on the books as a success. 

@ Bolded:  I do not agree with this statement.  First, Titanfall would need to be the type of AAA game that appealed to a mass market.  Even with the hype Titanfall received it still was a niche type of FPS on the X1.  Its online only with no Single player.  That right there killed a lot of people being interested in the game.  It required you to have GOLD which is another invested that killed sales.  There is a list of other things the game did not have or accomplish and its review scores were not AAA level to make it a must buy.  

I personally believe Titanfall and the 50 dollar drop is the same tatic MS has used many times before to keep console sells going but not something they were going to do permanently.  I believe MS dropped Kinect because it was not a good selling proposition overseas.  The device support overseas have been spotty at best and considered holding down sales where Kinect never really offered a lot of value.

Xbox One couldn't outsell the Xbox One? Interesting.

I won't say I don't care, I do a little we all do (otherwise we wouldn't be on a sales website). But I do agree I just want the Xbox One to sell well and maybe even get to 360 numbers and great support is a given really (well except Japan, MS will probably have to put some serious effort into that reigon)

The only way Japanese Developers would be exclusive to MS at this point is if they developed the game with MS money, cause they aren't going to sell well regardless. They might as well get paid.
