Right now the dilenation between devices is good for Sony, because people look at the Playstation and say "well you have to buy that to play Madden and GTA on your TV", but if that thinking starts to shift in consumers, then you have a problem even for Sony. If people start to realize their tablet can now also basically function like a console, it's going to be one less reason to buy a dedicated console. 

The issue is the competetion wouldn't just be the Switch. You're look at it through the narrow prism of traditional console wars. 

The problem is when players like Google and Samsung and maybe even Apple start saying "hey ... this is not a bad idea, lets try it". That's where you get into trouble, because people will then say "oh ok, my iPad already does this, I can play real Madden NFL on my tablet already". 

These mobile chips are getting better and better every year, soon enough they will be able to match/exceed a PS4, and sure PS5 will be a good deal better than that, but at what point do you reach a level in graphics where really it's good enough for most people. I think PS4 level is that cut off. 

The "big box under the TV" concept of console gaming might start eroding for sure. 

These are all reasons why Sony has to prove PS4 can be a replacment for your PC, and PS4 Laptops, Tablets, and Phones need to come as well. Sony has to change the idea of PlayStation from a dedicated gaming platform, to the best gaming first platform. This is what I have been shouting for the last 10+ years. 

Nintendo is in the same situation. They have to make Switch a device that can completely replace peoples Console/Tablet/Phone. There is simply no room for a dedicated game device anymore. If XBO and PS4 didn't have web browsers, Netflix, Vudu, PS Vue, Sling, Pandora, PlayStation Music, and so much more, then they would be selling next to WiiU numbers. 

Microsoft is already heading in this direction with UWA on XBO. I would not be surprised if the Scorpio actually ends up being called Xbox Surface, or Surface TV (Featuring Xbox). If the traditional gaming scence wants to survive, the concept of console has to change, and Nintendo, Sony, and Microsoft are trying really hard to help keep gaming alive. It is up to the gaming community to rally behind gaming devices as their one stop shop for all content.

Everytime we use an iPhone, or a tablet, or a streaming box, or smart TV, we are slowly killing the gaming industry. We have the power to stop it, but can gamers grow with the time? By God I hope so. A future where the only quality games made are Madden, Fifa, COD, becuase the rest are forced to go F2P with major downgrades, is not a place I want to live.

Yes. PS is going to have to rely on PSN for the future. Letting you play on whatever hardware you want is going to become the norm way down the road. For now the gaming companies need to give you choices to play on, but as long as you pay for the online service and games, they dont really care how you play the game. Eventually you will probably be able to play on any brand device, as long as you subscribe to the gaming co's online network, and buy the games from them.

Vast majority of the world is at best decades away from that ability.  

Thank God for the WiiU selling 130 mil amirite!?

Oh wait...one too many 0's.

You dont need to be a console engineer to know if your idea is gonna be a bad one or a good one. The fact that you couldnt even buy replacements for the WiiU Gamepad was proof enough that the idea was a doomed one.

Hopefully Nintendo will have extras sold separately but I wouldnt be surprised if they dont.

Making the tablet portion propietary - they will end up doing it like you would need the WiiU Gamepad for most of the controls in certain games which will of course turn off a lot of devs from making games/ports of their games whether they be late ports or simultaneous releases.

The thing I got pissed off the most with the WiiU (despite hating the controller design)  - is the fact that if your gamepad for whatever reason got damaged or stopped working, your only solution would be to ship it to Nintendo for a replacement or repair - you cant just buy a replacement from the store which irked me a lot. Its like Nintendo themselves didnt have faith in their system, if so, how can you have faith in a successor that will have a somewhat similar controller design?

Edit: Pretaining to other knock-offs - I dont want to see another disaster like the PSMove or Kinect - where they were trying to mimick the motion control success from the Wiimote ~.~. 

The tablet idea is oversaturated - motion controls were one thing but the market already has enough tablet type devices for various needs, I wont be surprised if the Switch ends up like the WiiU in that regards.
