To add in some new pictures from what was added by GymLeaderLily, here are a little bit extra, including some that wasn't shown in the newest trailer. [Credit to Serebii's site for the source]
Here we have the Magnet Train shown in its three dimensional figure.
I think it is pretty cool how they implemented this idea and brought more out in the Magnet Train, definitely an improvement went right.

You should note it looks as though the process is handled as if we were taking a boat instead, like in DPPt.
It was noted that this is the new Vermillian Harbor.
This is where I mention that not everything has been shown to be the same as FRLG in structure.
Like seen, we have Gold and Typhlosion going through Route 1.
The music, I hope is kept closer to the original, then it'll be a nice experience once more.
Besides this, I like how things are turning out. A bit of new mixed in with the old is pretty neat to see, and like said the OW sprites for the Pokémon are definitely in detail and seem to be working out just fine for an old but improved feature. I like the idea of animation being brought back for the rival as GLL had said, and I'm looking forward to seeing more. Less than a month people, we're almost there.
