Overall, it seems to be in the final 5% demo-wise. There's a lot more detail I'd like to add, but I guess it will have to wait until there's some kind of a release.
In storage terms, here's the flash page usage...
Page 1: 58% full (Main menu, non-battle code)
Page 2: 98% full (Battle code, enemies, graphics executables, physics)
Page 3: 85% full (Graphics data only)
Page 4: 22% full (Text data only)
Here is the main character roster. All the main characters from RW1 return in one way or another. The executable code includes a somewhat new subroutine simply called "Moveset" that can substitute Edgar for other characters, although he's the only one playable at the moment.
