Man, that is weird.
Some observations: it's not an RPG, it's a board game. (DenSETtsu is the RPG series.) If you really wanted to play it you could. Just roll dice and play minigames and shit. You could also play mid period Mario Party which is basically a Mario-fied version of this series made by Hudson themselves.
Also, I doubt it will be a port. That would be like porting Madden 2009 to something. It's a near annual installment sort of game, or rather it was.
Man, this is weird. I guess they are trying to rebuild and board games are cheap to develop...
