I'll go ahead and apologize for the wall of text to follow. I think I've narrowed down the main reasons of why I won't be doing anything beyond the 360/PS3 generation.

Social connectivity: The shrill screams of an unsupervised 8-year old child grate on my nerves just as much as 420budsmokerdudebro's non-stop verbal masturbation of his K/D ratio. Although I appreciate certain music lovers fanatical dedication and their need to share their latest mix tape over in game chat, their musical tastes are about one degree above beating a hollow log with a human femur. These are all people I wouldn't piss on if they were on fire; I wouldn't strike up a conversation with them while browsing the games at Gamestop or any other place, so why the hell would I want to talk to them while I play online? Remove their mic and they're the equivalent of CPU player with erratic patterns. On a general sense I have no need to share with the world everything that's happening during my game and I sure as hell don't care what's going on in others' games. If I was 16 I could appreciate the social aspects of gaming, especially being able to play with friends when you can't physically be with them, but as an adult I play games for the opposite: to get the hell away from people.

Game economics have changed: With a library or collection of games you're fortunate enough to always have something interesting in your backlog. Take what you already own out of the equation and there's not a lot of incentive to pay $60 USD for a title. You're options now are virtually limitless; used games, free to play games, free demos, rentals delivered to your house, <$5 digital purchases, etc. Why pay $15 for a single CoD map pack when I can buy an entire CoD game I don't have for $9? Why pay $60 for a title only to see it drop to $30 before you've even had a chance to get into it? That's not even starting on the endless see of free pirated games.

No time for mediocrity: My two favorite genres are 2D fighters and tournament-style FPS's, both of which are based around competitiveness either against a human or AI opponent. I totally get that you've got to practice, learn the systems and levels, ins and outs, I get it. But I don't have 15+ hours to put into a game just to unlock all the fucking characters. I don't have 15+ hours to unlock all the equipment you require to even begin to play competitively. The barrier in those games should be your familiarity and your skills, not the amount of time invested in them.

I don't get a lot of time to watch movies so when I do it's on a nice TV with a DVD/blu-ray copy and not hunched over a credit-card sized smartphone screen watching a camcorder snuck into a Taiwanese theater. If I've got 2 hours to game tonight I've got a decision to make: either I can go back to a game I know is going to be good, or I can spend 2 hours on something hoping it might be good. I'm no longer a kid that's forced to play shitty NES games because that's all I've got access to. Not to say I expect games to make me shit my pants with excitement at the title screen, I just don't have 20+ hours to put into a single game just to get past to the good part. I've got no time for mediocre experiences.

No software in genres I like: I wouldn't adopt the newest movie format if all they had on it was romantic comedies and Hogan's Heroes, nor would I buy a system that has zero software that appeals to me. No genres I like are represented on the new systems. Genres invented last gen that are now refined on this one, I'm completely content with playing on last gen because they don't hold much appeal to me anyway. Digital retro-releases have plateaued on previous gen and I would say for certainty we won't see levels of support for Virtual Console and it's ilk on this generation as we did the last... which is fine, because I already bought the shit once, and what hasn't been rereleased I have access to on the original hardware anyway.
