Mario Party 11 is in development and is scheduled to arrive in 2019. At least, that's the rumour coming via Marcus Sellars, a well-known industry insider, who teased the following information over on Twitter:
"ND Cube are developing Mario Party 11 for the Nintendo Switch and is scheduled for release in 2019."
Mario's next party game will come out next year according to unofficial reveal, which also suggests that the game is heading to the Switch, with ND Cube (a subsidiary of Nintendo) taking care of its development. Not surprisingly, the same Japanese studio was behind previous titles in the series, back on the Wii and Wii U respectively.
Nintendo has yet to comment on the speculation (nor do we expect them too).
Sellars also speculated that Call of Duty: Black Ops 4 could ship at the end of the year on PS4 and Xbox. Nothing unusual there, but Sellars also suggests that the game is also coming to Switch. The last game in the shooter series to land on a Nintendo console was Call of Duty: Ghosts, which released back in 2013.
