I begged off buying a new console when the PS4/XBone came out. At least for myself, I bought one of each for my office (I run a team of developers, so duh).
Frankly, I don't find either machine all that impressive from a technical or user interface perspective. Obviously it's likely that the software currently written for both devices is not as optimized as it could be and that over time developers will be able to eke more performance out of them, but the first few games we tried had horrible issues with frame rate stuttering and audio streaming that made me wonder why I had spent so much money on these machines, considering my 5 year old PC has better performance.
That being said I do know that traditionally console makers have used exclusives to draw in purchases, but when was the last time that this actually worked in any measurable way?
Honestly if you love games, particularly innovative ones, the place to be is still on the PC due to the dominance of Steam. Love or hate Valve, it's impossible to miss the fact that they've caused not only a renaissance in PC gaming, but also in good independent gaming releases. Out of my top 5 games last year, almost all of them were for PC exclusively or released without a publisher.
For me, right now it's not some "killer app" that will make me buy a console, the reason why I'm not buying one is because I don't feel any need to and I actually feel the market places for both PS4 and Xbox are kind of shitty. It's actually turning me off because they're so obviously inferior.
I'd be more likely to buy an Xbox to use as a media center for my house than to play games on...
