The only time they will ever be equal is when PS4 is 33% underutilized or when that that extra 33% is used for "bonus effects" that don't matter.
Doesn't matter though. I wouldn't care if the situation was reversed. I prefer games other than Call of Duty, Gears of War, Halo, and Madden over and over again.
I was burned last gen when Sony bombed the PS3 launch with all their under delivered hype and arrogance and got a 360 like everyone else... then... uhm... shooters and sports games? Guys where are the RPGs I have enjoyed since SNES?
Things are looking up this gen.
