Nintendo grabs trademarks for Hogan's Alley and Duck Hunt in Europe

Looks like Nintendo's up to something, and it involves some classic lightgun games. Both Hogan's Alley and Duck Hunt have been trademarked by Nintendo in Europe. We have no idea what this could pertain to. If this is in relation to Switch, it seems like the trademark has been grabbed quite early. No matter what platform these games are released on, they'd certainly need an update!
