It will be the successor with the drop of drawing map feature unless you want to spend half a day for a map only
Says the guy who obviously knows how development works and knows more on how to implement features in a game than the developers themselves. *sigh*
Etrian Odyssey and all spin offs based on it are known for its dungeon Crawling AND map drawing.That feature will have to evolve and it wont be the same as the games on the DS and 3DS.Wether it will be better or worse, who knows.But they will create a system that makes sense for the hardware and what its creators believes is best for the franchise.
Franchises evolve and adapt.Believe me, Atlus will find a good solution to this "impossible" problem.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
