What if instead of building in PS1, 2 & 3 backwards compatability they use thier acquisition of that game streaming company to offer these games streamed and PS4 abd Vita has access, so playstation plus subscribers have access to these and if you own the title you can pay a small fee to stream them to the PS4 if your not a plus subscriber.
It's entirely possible, yes.
If it will not work with used games I'm 1000% sure I will not buy it no matter how good it is.
Sony and Microsoft need to realize Steam store offer the users too convenient special offers and it's gaining market segments everyday. PC also take advantage of some serious killer applications like Assetto Corsa and rFactor 2. Not too mention pCars will looks considerably better on a proper PC.
You say that like games of that type make of break consoles. We all know they don't, FPS do.
