PS4 SOLD 7 million. XO SHIPPED 5 million. I'm sure you knew that though........ Anyway, MS released its console in its strongest markets. Sony has more appeal worldwide than MS does. How do you think PS3 passed 360 so much despite being outsold by so much in the US and releasing a year later. You just have to accept PlayStation is a more popular brand than Xbox. 

Seriously; did N64 screw his sister or something?

On topic, I think domination by one company for too long is risky. It can push out all semblance of competitors. Do you think if PS3 dominated as PS2 had that Microsoft and Nintendo would still be competing in the same fashion they're trying to today? Because gaming isn't a necessity monopolization isn't as dangerous as other industries. And there are a ton of other options to get games nowadays from your PC and mobile devices, so console domination would mean far less than it once may have to the public, should the leader's policies turn south.

Honestly it may not be terrible, but a market with good competition is probably more interesting. It's good to have a number of viable options, instead of one great option that might require you to sacrifice some consumer rights and a few smaller options with few games. In the age of online profiles, too, I think it'd be a bit harder for a monopoly to be broken once it's instated.

And things behind the scenes could be questionable, with regulation on development and distribution, and potentially the leader could charge mildly exorbitant liscensing fees for their console.

Titanfall sold #1 in March and Halo sells more then any PS franchise. Also Xbox one is coming out before sony in china which will flip the sales. Add in Dx12/cloud making Xbox one 4X more powerful. Xbox one will pass ps4 by the time this generation is over.

Sony is used to domination. They dominate because they understand what the gaming industry demands. Great third party and great first and second party. Give people something new every time. Thats why they always sell well. Sony excells where their competition lacks.

NIntendo lacks with third party

Microsoft lacks at first party

Sony excels at all parties, thus they are the choice even though some people go elsewhere for their games.

Nintendo.

And Sony.
