Like what? Only thing that really they pioneered was online console gaming.
I fail to see what they're doing that others are copying right now with great success.
The very same thing you credit them doing others aren't doing(Putting their games on PC day 1 and now even directly on the rival console.) are obviously not sustainable for Sony.
If you separate the online aspects from a console then it's just basically just a dumb box that launches the disc you put into it. So when you say online gaming you're really talking about the modern game console experience and most of the other things you can do on a console besides launch discs.
Sony really hasn't been that forward thinking. They weren't putting their first party titles on PC at all before Microsoft did it. They didn't have PlayStation Network before Xbox Live existed. Their consoles didn't even have a standard way to connect online out of the box before Microsoft did it. Launching apps on a console, a serious console OS, standard first party wireless controllers, The ability to purchase DLC and expansions, games installable on a hard drive, the console having a standardized hard drive out of the box, USB controllers that can also be plugged up to a PC.
There is a long list of things that Sony as the market leader should have been able to hang their hat on and say they did first but didn't and mostly did as a response to someone else (namely Microsoft) doing it first.
