Is the PS4 Sony's Most Successful Console to Date?

[PotentHerbs]

I think the PS4 is Sony's most successful console:

a) IIRC the amount of profit the PS4 made eclipses the profit of the PS1 & PS2 combined and it covered the losses from the PS3 era
b) SIE IP has seen major growth in part due to the PS4's dominance
c) Over 1.5+ Billion of software units sold
d) Established great reoccurring revenue in subscriptions like PS+/PS Now

Although the PS2 was hit by a lot of piracy which certainly hurt its software sales, and ultimately, the extent of profit it could have made.
