What's stopping me from purchasing consoles is I have no idea where my digital library will be when the physical system becomes outdated. I am out of space and there are games I want to play on all my systems. I am old school and I don't want to throw out things I paid for, even if its digital games, so far the games do not transfer to the new box when the box becomes outdated which is a huge problem when spending money on digital games. Its like its a sunk cost that you can never get back. I only have so much room for consoles in my room and I am maxed out right now. I have maxed out every electrical outlet in my 2 rooms with a power strip on each even after having an electrician to install more outlets. Multiple TV's are not an option, and no TV comes with 10 HDMI ports. I am barely going to be able to fit a switch when Pokemon moves to it. Some games are only digital so this is the only way to play them. Delisted games are also a problem as you can't get those on the new system no matter what. If you want to sell your console when you are done with it you lose all your games as well. Fun times. I bought a gaming PC last year to hopefully get rid of this issue and well, I kinda got into the video making and other things more than games on it, but its definitely the way to go for games these days, at least your library stays in steam and you will never lose it and PC hardware is not hard to maintain. I just have to try to actually play games on it instead of doing other things.
To be fair, the switch to AMD is supposed to make BC easier next gen. Xbox already says they’re games will continue playing on whatever next gen is, I imagine ps5 will have ps4 BC, physical and digital.
With games getting bigger and closer to 60-80GBs after updates I could see next gen using UHD BR as the main drive and game discs going to 100GB.
