So what is with thr graph there? Is it just inconsistent and indicating that the remaster increased sales to near 12 mil or did it actually sell 3mil more on ps4 than ps3?
It does indeed show that TLOU sold 8.15M on PS3 alone and 11.78M on PS4 alone.
But that's still "just" 19.93M in total explaining JRPGfan's "probably not quite yet". Furthermore, the numbers are estimates from Marth as you can see in this post. They seem to be pretty spot on though.
