''Sony Is Quick To Drop Hardware'' Is A Fabricated Myth

[Ck1x]

So they have been good at refurbishing hardware that they've created!
A lot of the things that you have listed have been poorly supported by Sony in the past,(Vita included). At this point there's no clue on how well PSVR will do in the long term, but of course the initial reception will be high it's new hardware. Even the Move didn't do to bad out of the gate, but in the long run Sony failed to support many of these added on functions with compelling software.

My problem with Sony is that outside of traditional console games, I don't think they know how to make unique games that take advantage of unique hardware. So I feel that with the PSVR like they've done with many other add on devices in the past, they will mostly rely on 3rd party publisher to push the platform. Which will probably result in some very lazy software adaptations for the VR system that isn't compelling.

This in turn I feel will be a negative factor on the much rumored PS4K, which will probably spurn many developers from even taking true advantage of the extra hardware. Simply because fear of alienating the original PS4 fan base could be at an all-time high if the PSVR doesn't get off to the right start. Unlike Nintendo, Sony will never go against the majority of its fan base in doing something unpopular, even if they feel it's a right move for gaming. Not saying that's an absolute plus for Nintendo at all, but if Sony can't sell current PS4 owners on PS4K being good for the future of Playstation. Then Sony might just put the whole project on ice if it's not well received...
