Digress your game is looking amazing! I love the new Zelda style gameplay. In regards to which style I liked more.. I say go for the 2nd one with areas or mid-bosses or big bosses with the first if possible.
I am glad you are going for a bigger game if you are going to lose F18A, but to tell you the truth those F18A screens looks very sweet, and for those of us going to get the Phoenix and finally have F18A support we would love to have as many games as possible to support it.
However you choose I am sure it will be awesome and unique like all of your other titles my friends and I love to play together.
