Update: a series of tweets from Tyrone Rodriguez further confirms that The Binding of Isaac: Afterbirth+ will be released on the Nintendo Switch, and more precisely in Spring 2017:
No doubt we will have a proper announcement in the upcoming months.
The Binding of Isaac Afterbirth+ is an extension for The Binding of Isaac Rebirth, adding new monsters, bosses, and items, but also a bestiary (tracks how many of each type of creature / boss the player has defeated). It will be released sometime in Spring 2017 on PlayStation 4 and Xbox One. What about a Wii U version, you ask?
Well, it turns out there will not be one. But the good news is, The Binding of Isaac: Afterbirth+ is actually coming to the Nintendo Switch! Tyrone Rodriguez said so on the game’s official blog, though he didn’t officially said “Nintendo Switch”. He wrote the following:
Expect Afterbirth+ on PlayStation 4, Xbox One and one more console
Naturally, that “one more console” can only mean the Nintendo Switch, as the PS Vita is ruled out, and the Nintendo 3DS isn’t powerful enough. We can expect a formal announcement next year, after the Nintendo Switch presentation in January.
Now, you’re probably wondering what happened to the Wii U version of The Binding of Isaac: Afterbirth (the first expansion), and it’s probably safe to assume it’s been cancelled (with the Nintendo Switch version including both expansions). We will have to wait until a formal announcement is made before getting more details about that.
