I think they need to focus on Virtual Reality and VR now that it's becoming popular. Why Xbox is slow to release a AR or VR headset is the reason why playstation is doing the best. Nintendo has one VR headset they released but is for kids.
i would like to see a table top console from Nintendo switch but it would be better they focus on a market that isn't saturated maybe doing a VR headset or something of that sort.
They hit the nail on the head though with the handheld combined with tv connection console. They have like a ton of patents too so you can't copy them.
With the success of the Nintendo Switch, I believe that Nintendo has the chance to release a top console in the future. I am hearing we may hear something soon in regards to a new console so I am excited for that.
