I'm already a Wii U owner. So a good majority of the games I'd want I already own on Wii U.
On the other hand...next-gen! You can already tell things are winding down this generation.
You seem to have already made your mind up with these statements.
That said... what generation is Switch technically a part of? It was released at around the halfway mark of this gen putting it technically as the only "next gen" system on the market currently but with current gen games.
I'm also putting a hold on game purchases after buying Ghost of Tsushima. I've been saving for my PS5 for a few months now but as we don't have a price point yet, all gaming money from here on will be put towards the PS5 launch. Hoping that the price point isn't above $500 for the optical drive model.
