I digressed here, but we have two potential outcomes on this path we're taking as consumers: We can either support digital only with no right of resale, or we can prolong the life of disc based systems. Your choice. They already got pc users to forget about disc drives in a lot of modern pc builds.
Both Microsoft and Sony have shown indications of bringing in resale/trade options for digital games. Microsoft stated outright they are working on a system. Sony haven't said anything official, but a year ago they did file a patent for a technology that allows the building in of an ownership portion into digital games- meaning that ownership could be transferred.
Anyway, despite having discs- the current generation has shown a huge increase in people buying digital on consoles, even higher than 50% in some markets. People are going that direction, the purpose of the Xbox SAD is simply to give people a $50 cheaper option if they only buy digital...plus there are now people that are using primarily Game Pass to play- the SAD is great for them. Yes you can buy bundles of the standard model for cheaper- when it gets out there the SAD will still be $50 cheaper than whatever the S can be sold for. And the SAD had a bigger HD as well.
My question is will the PS5 be bc with PS3?
Sony have only confirmed PS4 backwards compatibility at this point. We don't know other than that. My guess is that emulating the PS3 is too hit and miss, they probably have something but it only works well with a few games.
I am never going to digital fully for various reasons, one big reason is license expiration. "Scott Pilgrim" is a great argument for why we need discs, the licensing now being an absolute clusterfuck likely because Universal sees the demand but is demanding too big a wad of money to see it re-released. In other words they are greatly overestimating sales numbers. I haven't even brought up patches for releases on disc that need to STOP.
As for PS3 I'm not re-buying my games for it, I will wait for an FPGA that handle it. Sony can suck on a lemon if they think I will re-buy "Ni No Kuni", "Demon Souls", "Lair" and the many other PS3 exclusives that haven't been ported to other platforms. The sad thing is the PS3 is chockful of PS2 goodness with the PS2 classics to buy which is still much better then the PS4 store for them. Case in point, pretty much the whole big Atlus slate, Tecmo's "Trapt", Suikoden 3-5, Eternal Ring, Evergrace, Fatal Frame 1-3(why are the first 2 missing from the XBox store), etc. All that is on the PS4 are like 10 games..."Parappa the Rappa"(which has a timing problem), "Fantavision", "Primal", "Me and Satan King(i.e. Okage)", Wild Arms 3, "Dark Cloud 1-2", etc. I would love to see rares like 'Haunting Ground", 'Rule Of Rose" and 'Blood Will Tell" where Atlus realized there was money to be made reselling their rares unlike Capcom and Sega.
edit: At the end of the day the PS3 had a much wider and BETTER set of exclusives over PS4 and I love my PS4. I think this is part of the reason people were so pissy how "bc" was handled by way of PSNow with a fee....ugh.
