Nope! Quite the opposite, in fact- I'll be eyeing out for deals from the people who do start unloading their soon-to-be last gen gear!
I'm utterly unconcerned with a game's age, I just play what's fun. The only system I ever unloaded fully is my childhood NES. It was a family console & a family decision to sell it & get a Genesis. While we loved our Genesis, we deeply regretted selling the NES.
Any console that became truly unessecary via backwards compatibility I've given away- and I've ended up rebuying all but one of those! I sincerely doubt I'll be getting rid of anything when the new stuff arrives.
