I found this on the freshly opened Starfox Zero japanese website, and I think they are pretty cool (but short) gameplay footage :

Very nice.

This game has gradually changed from a title I was contemptuous of to one I am actually anticipating.

Man, they sure are relying on Star Fox 64 a LOT. I understand as it's the best game in the series imo but a lot of things just seemed to be pulled from 64 without change.

As expected, the visuals have been improved and they can get better over time by April, but I'm much more interested by how much more aggressive the player seems to be able to be. I think the controls will be intuitive. Hopefully it's easy to learn hard to master rather than tedious

Visuals have been improved, especially the lighting, but doesn't look super amazing..

Gameplay still looks fun though

Given that it has improved noticeably in the 5 months since E3, it stands to reason it could improve yet further in the 5 months remaining before release. It won't magically look like Bayonetta 2 when it comes out, but it could still get a little better.

Nintendo must know that a big part of its negative reception at E3 was due to its graphics, and it looks like they're at least trying to address this.

Looks average. Gameplay is stuck in N64 era. And visuals are still underwhelming.

This is a good thing if you ask me, games in general were better back then. ;)

Another one.

Not necessarily a bad thing because like you said Starfox 64 was awesome, but yeah, I was expecting something a little more than just a Starfox 64 with different level layouts. Multiplayer still isn't even confirmed.
