..expected GTA4 to lose to a arena fighter ...

..PS4 and Xbox One would not outsell the PS3 and Xbox 360 mainly due to sharing the same gaming library...

Ahem

How many PS4/XB1 sales are due to Fortnite?

The last shipment numbers from Take Two in 2012 was that the game shipped 25 million so... Ahem

And for your second question, we don't know, probably the same as Grand Theft Auto 5 , NBA2kXX, Madden XX, COD XX, FIFA XX and countless other games.
