PS4 has sold far above expectations this year. Already 5.6m sold-through in 2020. Some people thought it wouldn't surpass the PS3's 2013, which at this point was only at 3.6m.
Could be at 117-118m sold-through by the end of the year.
Probably will overtake the gameboy and become the 3rd best selling console of all time in the first couple of months next year.
