Im kinda surprised the PS4 hasn't overtaken the PS3. It seems to do pretty ok in Japan.
PS4 is definitely overdue for a price cut. Plus, last gen the home console market was in a slightly better position. Not by much, but PS3 was able to pull off 10.5M and 360 did 1.7M. This gen, XBO will be lucky to hit 250K. PS4 may leg it out to tie PS3 if they actually drop it to the equivalent of $199-$225 next year and it gets a boost from FF7 and Ghost of Tsushima.
