Wii U, PS4 and XB1 are all getting many huge exclusives in 2015. But which one of them will be the best-selling exclusive? The following are all exclusives for their respective consoles, scheduled for a 2015 release:

Wii U: Xenoblade Chronicles X, Mario Maker, Kirby and the Rainbow Curse, Splatoon, Yoshi's Woolly World, The Legend Of Zelda, The Devil's Third

PS4: Bloodborne, Uncharted 4: A Thief's End, Everyone's Gone to the Rapture, Ratchet and Clank, Hot Shots Golf, The Order: 1886, Let It Die, Until Dawn, Rime, Deep Down

XB1: Scalebound, Halo 5: Guardians, Fable: Legends, Below, State Of Decay: Year One Edition, Quantum Break

Uncharted 4 IMO. Halo 5 possibly a close second. This will purely be down to differences in user base though. I.E Uncharted 4 selling to 30% of the PS4 user base would be the equivalent of Halo 5 selling to 60+% of the X1 userbase.

Uncharted 4, then Bloodbourne. After that a Wii U game or Halo.

Uncharted 4, Halo 5 and Bloodborne.

Zelda, then Halo, then Uncharted. I don't think the user base will have a huge impact on the sales of exclusives. But Zelda is the Zelda Zelda fans want while I think Destiny is the Halo Halo fans want.

Halo has always been bigger than Zelda, and Naughty Dog have got a lot of new fans thanks to TLOU, so that should also impact sales of Uncharted 4.

Halo 5.

uncharted 4, i think.

but can you really see Zelda passing 5m on the Wii U? 

With Uncharted 4 and Halo 5, its a given.

It will be between Uncharted and Halo 5. Halo 5 would win 1:1, but Uncharted has the userbase advantage.
