No, they won't. And even in the highly improbable case that they will, it will only be for a brief period before they return. This is because the more you reduce the amount of physical game releases and/or the size of the physical printrun, the higher the percentage of high-paying customers (the gamers who buy the most games) for physical games will be. At that point it becomes simple economics where game publishers will think thrice about cutting off their most valuable customers. Nevermind that there's a lot of value for console manufacturers to have your console cardboard boxes surrounded by lots of games in stores.
Physical vs. extinction has taken on the life of Michael Pachter's infamous "this will the last generation of consoles" prediction that he kept making each generation. So you can expect that the end of physical games will be routinely predicted to happen in the not-so-distant future.
Legend11 correctly predicted that GTA IV will outsell Super Smash Bros. Brawl. I was wrong.
