I'm very much in the same boat. I'm not feeling either launch to be brutally honest. Second Son is the only next gen game I've seen that really makes me think I actually "need" a next-gen system, and that game isn't coming out till February (TitanFall also looks great but I'm not really a multiplayer guy).
Having said that, I bought a Xbox on day 1, and I got a 360 on day 1. How can I not continue that tradition? I've bought all 3 Playstations on their respective launch days. How can I not continue that ? I'm not going to be a big spender on next-gen games though.. I'll buy the damn hardware, cause I know I'm going to want it eventually. The first price drop for these things could be far away, so might as well just get it over with. I'm going to play every demo they offer, and maybe rent a few games here and there. Other than that, I might buy one or two games, but that's about it.
