For me it's a bit weird, since we're only a few years into this console generation. But I've never been a big graphics junkie, so I won't mind not having it...
My concern is that developers will start prioritizing game specs for the Neo, resulting in games that run well on the Neo but perform poorly (Bethesda-length load screens, frame rate choppyness, etc) on the regular PS4. Sony has reportedly given a mandate to puiblishers that their games must run a minimum framerate on the Neo, but I know of no such quality mandate for the original PS4. I suppose the market will determine which PS4 is prioritized by developers, and I suspect most people will stick with the PS4s they have. But the possibility remains of games running poorly on the PS4 that would have been quality controlled better if the Neo didn't exist. So label me with a big "we'll see".
The Nintendo NX console has just been given a March 2017 release date. I am VERY curious about what Nintendo is going to roll out. Unfortunately it sounds like they won't be sharing NX details at E3 this year, focusing instead on the Zelda game that was just delayed until the NX comes out... (Sigh)
I have the feeling that if Nintendo doesn't knock it out of the park with the NX they could become a game software company only in the near future... which honestly I think consumers would love. (Can you imagine being able to play your favorite mario games and all new mario releases on your console of choice?)
Xbox is a real point of curiosity for me. For the sake of getting Sony to do the same thing, I hope Xbox reveals "1.5" Xbox as well as some kind of external box add-on for less money that upgrades existing xbox ones to the 1.5 specs. This is what I think Sony should do too, instead of asking customers to buy an entirely new console to keep up with modern console gaming.
As for PC gaming... well by the look of things we'll ALL be playing on PCs of some kind in the near future. They might still call them consoles, but we'll all know better, won't we?
