THE GOOD
>Autosave is confirmed, touch screen features from SF1 switch to button presses, Free Camera mode lets you scan the whole area like BN5 liberation missions, Geo/Megaman has a sprint option, various ways to change the two top and bottom screens and can use vertical screen display option (tate mode) to emulate classic DS, easy mode is being planned as well as options for no random encounters and the return of buster MAX, no longer have to manually switch between navigating in-game menus and interactions as they're automatic, remade title screens for the games, Koji Oda who directed MM11 returns to direct the SF Colleton and FULL ARRANGE BGM OF EVERY GAME.

THE BAD
>Can no longer edit your name as Geo is now the default, removed the On Air local multiplayer feature, and removed the custom profile editor

THE UGLY
>Profile icons with filters exhibit AI upscaling, graphical errors, and rendering issues stemming from the 2D/3D models.

Most of the flaws might likely be looked at, which is why there's no release date. And even with the bad parts that's shown from TGS, there's a lot of potential for this being way more than a rom dump.
