The best thing about all of this is the silly fools who were like "All Sony games will release on PC day 1 and soon." Crazy how some people struggle to understand the significance of the Playstation platform to Sony.
That said, Playstation will ultimately transform to a storefront with some if not all their games being exclusive on it. Wouldn't surprise me if the PS7 is a closed PC that only supports the "Playstation Storefront", and has the same price range and convenience of home consoles, therefore Sony wouldn't lose their core audience, and might instead become a significant force in the PC space where the store is also available outside their own hardware (Sony wouldn't care if you stop buying their hardware as long as you remain in their larger platform).
Consoles have one major weakness against PC that hardly gets discussed: It's the requirement of development kits. Recently, many of those trendy games come from indie studios that start on PC. This gives Valve/Steam a big advantage against consoles which often get these games a while after they established a large audience and connection with PC.
Now someone might say "isn't this what Microsoft is doing with the next Xbox?" The answer is not quite, because:
1. Microsoft will not be able to sell "consoles" in the tens of millions. Xbox is a dying brand and their offerings will be expensive.
2. Microsoft will allow 3rd party storefronts. This is a double-edged sword that will remove more Xbox players than it brings. The storefront, NOT the hardware, is where the real money is made. Valve will benefit more from this than MS.
3. Unless they do some radical changes, Mirosoft's games aren't locked to their paltform. Valve, Sony, Nintendo and even EpicGames (on PC) all recognize the value of their own games as platform/storefront sellers. Microsoft doesn't, they seem to care more about reach and their 3rd party aspect.
4. Sony may continue to work closely with AMD to design SoC's that are cheaper to produce with an unparalleled "power per dollar" aspect. Retaining a traditional console advantage.
Call me crazy (and I might be), but I don't even rule out Sony taking this path with the PS6. But I think doing this early would confuse and be a PR disaster.
Storefronts will branch out to more hardware, but exclusive content will never die.
