He's got a point.
The wall feature could make dungeons too easy and utilizing the same overworld isn't a great idea. It should be revamped like Hyrule is in every Zelda game. IDK, I guess it will have to wait for E3 to see more.
I know I love Zelda and in particular LTTP, so I am now planning on getting kids all 3DSs (3 of them) just so I have access to this game.
