Sounds like the game is pretty much ready and the Switch 2 version's performance issues are holding it up.
The first two were in Spring 2020 and Spring 2024, so this one being Spring 2027 puts it about a year earlier than I expected. COVID kinda added a year to all of the normal timing cycles, though. Devs that usually put out a game every two years roundly put out something on the third year instead, etc. Getting this a year early is cool, and means I'll have to move up my Rebirth replay. Only played it the one time, been wanting to go back and get the plat for a while now. Thinking maybe I'll do that in the month before this new one drops, so I can go right from one to the other, but either way I've gotta put that on my list for this year now.
I really hope they get the whole northern continent part right. While Disc 2 of OG FF7 was my least-favorite part of the game overall, I liked the first few hours of it a lot. All the snow areas, while sometimes tedious and annoying, really felt desolate and striking after the shock of losing Aerith. Wandering in a cold wasteland was like a physical manifestation of how the characters were feeling at that moment. So yeah, really looking forward to the snowy northern continent being the first few hours of this game (at least) and being fleshed out more. After that I expect the game to branch out into almost an open world mission-based game like FFX-2, where you have Highwind and an array of "hotspots" to go to and resolve various problems that are going on, like WEAPON appearances and story sections that didn't make it into Rebirth like Wutai.
Expecting Wutai to be a huge part of this game, not just the one section we got in the original. It's a kingdom powerful enough to fight off Shinra's military, and portrayed as being fairly huge in this version. There'll probably be a lot of new content added for that part in particular.
A Dirge of Cerberus Remake would have made sense for Fall '26, or Christmas, but it looks like they aren't bothering. Maybe that game just wasn't save-able, or they didn't think it would be worth doing like Crisis Core was. Also bummed that we're not getting any DLC for Rebirth. One telling the Rocket Town story with Cid's backstory would have made sense and I've seen a few people saying as much. That part of the story was just left out, and important for understanding Cid. The third one can still do that part, with Cid going into space, but it would have made more sense to do it in Part 2 as the introduction to the character. Now it'll need to be considerably different since he's already been with the team for a while. Cid got like no development in Part 2. So yeah. In my dream world they would have done an "out now" Rebirth DLC along with the Part 3 announcement and given us that Cid backstory.
I think I saw a Jade WEAPON in the trailer. Jade WEAPON was in one of the Japan-only spinoff games no one played, like Before Crisis maybe. There's room for adding that, Citrine WEAPON (a yellow counterpart to it), and Sapphire WEAPON. Really hoping we get Sapphire WEAPON because the original game had it, but it was never fightable. It's the one that gets shot by the Junon Cannon near the end of the game and presumably sinks to the bottom of the ocean.
Also the snowboarding minigame needs to be excellent. The original could have practically been its own game release. If this new one nails the snowboarding minigame, people are going to spend hours just playing that.
