For the 8th gen I have two systems right now;
3DS - Got it the day Ocarina of Time 3D was released, got it solely for that game. A Zelda game alone to me is worth the price of the whole system. Luckily the 3DS shaped up to be one of the most awesome systems yet.
WiiU - First system I got on launch-day since the N64 because I wanted to try out the GamePad and thought NintendoLand looked very promising. Wasn't disappointed, but it's taken a while before anything else worthwhile got released.
For the 8th gen systems I haven't gotten yet, I won't be getting any of them at launch, and they're all still up in the air if I'll get one at all. I'm not liking where this generation is going policy-wise and with 'unfriendly' stuff like game installs, HDD requirements and the online/social focus.
PS4 - Won't get it at launch because there's no games that interest me. The power difference between 7th gen and 8th gen is negligable to me, and the system doesn't have any interesting new feature. A new Uncharted recently got announced so that greatly improves the chance of me getting one sometime. Still needs more.
XBox One - Same reasons as the PS4. Probably never get it, especially if I do get a PS4.
PSVita - Interested in the hardware, but there's still no games that interest me. There's only Uncharted, which is not enough. If the system gets at least two more games I really want to have, I'll consider it. Sadly, with each passing year it doesn't seem to be the case that'll ever happen. So unless I can get one for next to nothing I'll probably never get this.
