Nintendo will always stand above the other two glorified entertainment boxes. Nintendo systems are video game systems at the forefront rather then an added feature in the others.
PlayStation is games but still a glorified entertainment box, if I had to choose between Xbox and PlayStation I’d go PlayStation since it’s worth it.
Xbox is just a glorified entertainment box, they have little to no games worth anyone’s time and money in it and people only buy them to play movies (it’s been that way since the original which had games worth the time and money)
All in all, if Sony/PlayStation decide to go the hybrid console route it wouldn’t be popular, remember the PlayStation vita! It was the most powerful handheld and still got beat by the DS/3DS!
Nintendo will always have the upper hand where the others don’t!
