Square Enix has trademarked Collection of Mana in Europe
If a recent trademark is to be believed, Square Enix appears to be bringing the Seiken Densetsu Collection to the west. Released back in 2017 for the Nintendo Switch in Japan, the Seiken Densetsu Collection is a compilation of three titles from the Mana series, as it is known in English territories: Final Fantasy Adventure, Secret of Mana, and the never-localized Seiken Densetsu 3. On May 31st, Square Enix registered a trademark in Europe for a video game under the name of Collection of Mana, which hints at the games possibly making their way westward. If this is true, then we'll likely see an announcement at Square's E3 press conference.
