The way they put em out there.. you would think Sackboy...

Polygon Man!

If I don't even know who that is... he's a lousy mascot.

I don't think Sony needs a marcot any more than Colombia Pictures, Netflix or Electronic Arts need one.

From the Pedia of Wiki:

Polygon Man was the former mascot for the Sony PlayStation in North America. He appeared in the consoles pre-launch ads commenting on various launch games but was dropped before the launch of Sony’s first console and replaced by a series of popular game characters starting with Sofia from Battle Arena Toshinden, Parappa the Rapper, and Crash Bandicoot.

Phil Harrison, then head of Sony's European game publishing business, recollected the reaction of Ken Kutaragi, global head of the PlayStation brand, when Kutaragi saw the Polygon Man for the first time.

“I remember walking onto the E3 booth in 1995 with Ken and seeing the Polygon Man design on the side of the booth. Ken just went absolutely insane,” says Harrison. Kutaragi was upset that SCEA was spending its limited budget on an alternative brand. “But the thing that really upset Ken was that the Polygon Man design wasn’t Gouraud shaded, it was flat shaded! So Polygon Man was taken out into the car park and quietly shot.”

In 2012, Polygon Man resurfaced as the main antagonist and final boss of fighting game PlayStation All-Stars Battle Royale.

Truly a legendary figure of this gaming age.

I would say Nathan Drake or Kratos, but neither of them are as relatable to the Sony brand as Crash Bandicoot or Spyro were. Sony really should have kept those IPs

kevin butler?

or "the invisible man",you can find his picture and his name written on every playstation(with invisible ink)

They haven't really got just one like Nintendo had. I would Sackboy is sort a mascot but others would say Crash Bandicoot was at one point. Or possibly Kratos or Nathan Drake or even Solid Snake. It's not set in stone really.
