Rocksteady's new game. It's been 3 years since Arkham Knight, so I expected to see something.
Mortal Kombat 11 as well. NetherRealm has a two year cycle with an E3 reveal on even years and releasing the game the following spring, on the odd years. It's surprising to see they are abandoning that cycle.
Yoshi for Switch as well. We never saw that game after it's initial reveal, ever.
Yeah, Yoshi was delayed which sucks. Pokémon would have been extremely high on this list too if they didn't say from he start it would be a while before they show it off when they announced it.
As for Rocksteady, who knows what they're doing.
