I'm glad to see that the reception to Star Fox: Zero during previews has become increasingly positive, and - as all those extremely thorough GameXplain videos show - it has definitely improved visually from its underwhelming debut at E3 last year.
However, I'm still not convinced. I might get crucified for this (way to start off coming to this forum, haha), but I don't like Star Fox 64 anywhere near as much as most people seem to. Which is weird, because I feel I have a lot of affection for Star Fox generally, and consider it one of my favourite B-tier franchises. I didn't play 64 at the time of it's release (I would have been, what, two years old!?), but did manage to pick up a cheap copy when I was about ten - but it did nothing for me. When I bought Assault, however, I fell in love - yes, it's been about a decade since I've played it, and I can admit that the ground-based levels aren't very interesting, but I loved the (all-too-few) on-rail sections and the whole visual spectacle of it all.
I later played Adventures and Command - both of which I enjoy to a certain degree on their own merits - and even re-played 64; in fact, only a few days ago I picked up 64 3D and played through all of the levels again, just to see if I feel more favourable towards it after all these years. I don't. I think it's good enough, but its Arwing combat isn't as good as that in Assault, and it's nowhere near as good as some other third-person 3D on-rail shooters, like Sin & Punishment.
From everything I've seen, Star Fox: Zero seems a lot like Star Fox 64-2 - and I don't want that.
(Also, can I just saw that I really don't like the voice acting in Star Fox 64 (and now Zero)? I hate to talk about 'characterisation' in Star Fox games - because, I mean, jeez, they're STAR FOX games - but I really preferred the characterisation - gah - of Fox and everyone else in Assault. I have a lot of fond memories of Assault. I really liked its multiplayer, too).
