Sega has delayed the release of its Mega Drive Mini console, which the company announced back in April, to next year. While the push to 2019 may sound like bad news — Sega will miss the 16-bit console’s 30th anniversary in Japan due to the change in date — it sounds like Sega is doing the right thing by its classic console.

Sega is now aiming for a global worldwide release of the Mega Drive Mini in Japan and Europe, as well as a Sega Genesis Mini in North America, according to a pair of tweets from Sega’s official Japanese Twitter account.
