Chariots and bronze weapons in the arena
The first wide shot resembles a classical city-state. As the camera enters the arena, clothing and bronze weapons move the overall style away from Fódlan’s medieval impression. In the first proper battle, 
Cai attacks with a lance while riding an Ornius. The defending 
Charioteer carries 
Bronze Bow, bringing a classical unit type directly into the combat system.
Bronze Spear displays an effectiveness notice against a mounted unit. That is a notable change: favorable matchups may depend on weapon types themselves rather than only a few specialized weapons. High Critical and personal abilities also stand out. From one battle alone, it is more useful to see how they appear together first.
The queen’s gambit sends her battalion forward
On 
Theodora’s command, her equipped battalion charges forward and disrupts the enemy. This turns a gambit from a button on a character sheet into visible team action. Her displayed class is still 
Noble despite being level eighteen. The relationship between class and level deserves watching rather than assuming it follows an earlier game’s pace.
Blaze can summon large monsters
A new command appears in 
Dietrich’s menu. Weapons still have durability, while personal abilities and critical hits make the scene striking. For 
Leda, the menu changes to a set of song-related moves, and Blaze looks different too. The protagonists clearly have distinct tools.
The monster summoned by Leda occupies four tiles. That interests me more than simply adding another damage skill. Where we previously had to surround and dismantle large enemies, now a large unit can fight on our side, making blocking, positioning, and area coverage more interesting.
Character personalities and story conflicts
I like Leda’s dancer-like presence and Theodora’s cool, commanding queenly style. Three main characters have different banners behind them, while story footage hints at grievances between them. Leda even has childhood memories, raising questions about what each character is pursuing.
Sothis sitting on the throne at the trailer's end is the story clue that interests me most. I lean toward this taking place after Three Houses: she looks older and reminds me of her form after merging with Byleth. Ancient Greek architecture does not directly prove a prequel. The futuristic magic pistol makes me wonder about time travel.
Class balance needs to account for repeated routes
Combat itself is appealing. Next, I hope the classes and numbers are balanced so different paths are worth training, and battalion gambits remain useful beyond a handful of monster fights. I enjoy character interactions, but repeating lots of identical actions on every route while losing training progress could quickly become tiring. How the new game changes those areas is what I most want to see.
