The Madden 18 release date is in August. There is no official announcement yet, but for the last 10 years, the new Madden game arrived in August.
The odds are very good that the Madden 18 release date is August 22nd or possibly August 29th. We do expect another early release for some users. EA Access on the Xbox One offers the ability to play new EA games five days early, which means many gamers can play on August 17th or August 24th if all holds the same as last year.
You can expect to get your first glimpse at an official Madden 18 video in late April or early May. EA typically offers a teaser with a little bit of information about the game.
