Managed to get one from Amazon this morning so that's good. Now I'm just trying to decide what to do with all my old consoles. I've got my PS4 Pro and Xbox One X along with an Xbox One S and a regular Xbox One kicking around somewhere. If I offed all of those now it'd easily fund the cost of one of the next-gen consoles (I'll be buying both) and I'd never use them again anyway. Hmm.
I don't normally ever sell any of my old consoles because even if it's years down the line I end up regretting it. This time around with full backwards compatibility I don't think there's any need to keep the Pro/X.
