If Switch can manage to reach 3DS numbers I will agree. I doubt it though. Just like Handhelds died due to Sony and Nintendos inability to offer the most basic features, I see PlayStation falling off a cliff as well. Nintendo already killed off their Home/Handheld business, and have went to a Hybrid catch all platform, to get whats left of their userbase on a single platform.
Microsoft is the only current console company looking at the long term health of consoles. Sony and Nintendo will be replaced by Apple and Google in due time, if they don't expand their platforms.
Yes! We finally have our playstation will fall off a cliff comment!
