Won't waste money on the "New Switch", since it's most likely going to be a minor upgrade that nothing takes advantage of because, gasp, the majority of devs don't like a fractured userbase, so it'll only be utilized by like 4 games and then fade into obscurity. Y'know, exactly what happened the last two times Nintendo did that, and what happened with the PS4 Pro and XboneX.
XbTwo and PS5, I'll probably grab just the PS5 if MS keeps up the whole "PC and Xbox market should be one" thing they're doing, and if not and any decent XbTwo exclusives come out I'll pick one of those up, too.
But my main gaming is done on PC, so either way I probably won't use either too much. Yeah it'll be a "waste" of money, but I don't really care that much, I just like having all the consoles for collections sake. I'm a gamer, I like games, I don't wank over one company or the other.
