I'm personally of the opinion that Sora's new Keyblade that was shown off in the trailer could be a new original Keyblade, akin to the Star Seeker. My main reasoning is its particle effects.

I've seen many people talk about the fire flowers but not many talk about the water shurikens!

This character, who I'll refer to as Vali for now, is shown to be wielding a weapon with shuriken shaped teeth and keychain. And we know Vali is designed to look and very much attack like a ninja in Dark Road, so this makes perfect sense.

I believe this Keyblade could be a new original Keyblade Sora obtains upon meeting Vali and an unknown character. This Keyblade seems to have a lot of terrain altering properties, so it'd make sense if Sora starts using it as soon as the player is introduced to the Scrap and Build mechanic via Vali and the other unknown character.

Though the fire particles do somewhat remind me of Remus' Keyblade's particle effects from the Missing Link beta, even though it's not completely identical. Maybe we'll meet a character that we would have met in Missing Link? This Keyblade would have been equippable (and upgradable) by the player, so maybe it would have been wielded by another character as well.
