I would say around 35. We will likely get around 10 Nintendo Games (2 Zelda, Star Fox, Pokken, Genei Ibun Roku #FE, Mario & Sonic + 4 other), some Indie Games on Discs (Mighty No. 9, Terraria + other), these games launching every year again (Just Dance, Skylanders, Lego, Disney Infinity) + some other games. Should be around 35.
Please Note: I'm talking about western Disc releases.
How many do you think will launch in 2016?
