To be fair it was the wii wich was the last console withouth any patches for the games only in some occasions for the system menu and eshop.
Xbox 360 and ps3 had patches for their games so it's not fool proof but that's not the main thing in my opinion what would affect the collectibility since I'm pretty sure there will be an easy way to get those patches on the console by other means pretty easily so i would not worry about that to much.
also i'm pretty sure the ps3 and xbox 360 will not really be remembered like allot of other consoles. The best games are remastered on newer systems or just don't hold up well since there are superior options or so many games wich look alike. These days the choices are endless for certain genre's of games wich might make games less memorable.
There are ofcourse some exceptions and there are some unique games but i'm almost 100% sure the xbox 360 ps3 era and above will be looked differently as far as collecting goes thanks to the abundance of choices on the ps4 wich truly enough releases allot of interesting games. i also wonder what will happen with all those CE of the ps3 and xbox 360, I'm pretty sure you can't get rid of those after some time
There will be exceptions but overall I don't really think ps3 or xbox 360 will be looked back on the same way as ps1: or especially the ps2 or original xbox wich are already a great example of being treated a bit differently as far as the people who collect for those systems goes. It's very selective, pretty much no full set collectors and just less popular overall compared to other systems of that era while gamecube and dreamcast seem to actually be the last systems that people really collect for like the older systems. ps2 and xbox are a bit in between still pretty collectible but allot more selective. wii also fits the ps2 and classic xbox pretty well as far as collecting older games goes .
I'm pretty sure in the xbox 360 ps3 era onwards it might be allot less than those systems or pretty much gone it will be a niche or at the very least pretty cheap to get into. It will not be as collectible like allot of the older consoles. yes there will be some games here and there but it will be very very selective. ps2 wii and og xbox are great proof why i think this will happen.
those systems are a great example of retro game collecting being treated a bit differently less people getting into it, barely any full set collectors and just pretty selective compared to the older systems,i can't really see those being less collectible than the ps3 or xbox 360 those will be far farr less collectible. I'm pretty sure that many people will still collect for xbox 360 and ps3 in the future, but only for the sole reason that the games will be dirt and dirt cheap and a very niche group for the more expensive collectible games if the games have not really been remastered etc for certain genre's or the most rare games for the consoles.
