I have to disagree. There are way too many reasons this would fail, though you do raise some good points. The benefits of one console would be the same as if Ninty stopped making home consoles and released their games on ps consoles. That way, the ps4 would get no drought, the xbone would not be able to compete and you would end up with one console.
Ninty home consoles haven't done well since the (s)NES and the only reason Wii did well was the novelty of the controllers. They might be lucky and come up with something revolutionary again, but overall it's a huge gamble and the more they make home consoles, the more they hurt the brand. Unfortunately the wiiu is at the moment the laughing stock (pretty much same with vita).
