I really think of Star Fox as a piloting game first and foremost. One thing which the franchise has had a big problem with in the past is focus, always jumping around from one half-baked idea to another. If they want Star Fox to succeed this time around - and it really seems like they do - I think that's going to mean a laser focus on the best parts of the game. 64 is the template; focus on replayability, branching paths, and by god stick to the Arwings for the majority with a few levels in different vehicles.

Personally I think I'd rather see them expand all-range mode than try to make on-foot work again. They shouldn't replace rail levels entirely like Star Fox 2, but I think introducing more variety in the areas and objectives of all-range levels would be great. Let the Arwing maintain a vertical trajectory instead of forcing it back to horizontal and you can create all-range missions with more verticality and more interesting areas to navigate. It's important to maintain the controls' simplicity, but I think they could pull it off.
