So I've been theorycrafting a bit and there are some ideas that are standind out in my head:

Nb: We have a leak (real or fake IDK, but it is here) about LeonCrest being the UX 06 so I won't say anything about UX06.

So, based on previous schemes in releases, the 3x3 Battle Deck Sets are often a mix of new and old. Here is my attractive theory about UX07:
We will get a new UX bey, we can have a recolor of an older UX (Hells Hammer for example didn't get any recolor yet) or older BX, and... As Burst did many times, they can re-release a rarer part, like Cobalt Drake (recolor, not painted). It would be a nice time to sell it: Team Pendragon will be on screen at this time (even tho it will be Cobalt Dragoon). This would sell incredribly well.

And for BX36 I would see a Suzaku bey, as a last reference of the original Beys, the last one missing: Dranzer.
BX would absolutely make sense as Weiss Tiger, Cobalt Dragoon and Black Shell are BX and not UX.
-Weiss Tiger is a reference to Driger V and its "all purpose attack" feature
-Cobalt Dragoon is a reference to the Dragoon line, and especially GT, if you ask me
-Black Shell is an abvious reference to Draciel F

So, following this scheme, BX36 would be a reference to a Dranzer beyblade, but as the line changed a lot in designs, it's really hard to anticipate which one they will draw inspiration from. My guesses would be V, V2, G or GT, since those designs change a lot from each other, they would also find a nice spot under a BX release :)
And for the naming: we would keep the scheme "Color + Animal/Attribute", Vermilion Bird would be a perfect name ! But a lot of things could be considered: "Ruby", "Crimson"... But there are too many ways they can name it, so I won't go on any further here !

I hope this little theorycraft break entertained you !

:)

CX ideas

Spoiler (Click to View)

I have 3 main ideas for CX, which I speculate to mean Custom X.
First Custom: A separate piece for the motif (like face bolts or chips). These would not only be a way to swap motifs, but also would be the pieces that hold the teeth and dictate Burst resistance.

Second Custom: 2 part Chassis. With Leon Crown we've seen TT can create large Chassis, so I could see them mostly sticking to normal sized ones, but also adding extension parts to greatly increase the Beys size (think frames).

Third Custom: Multiple modes. This could go for Blades, Chassis, and Bits. Just adding multiple modes to switch between. This is a classic for Beyblades and usually gets added in around year 2-3 anyways.

Quick expectations for Season 2

This all assumes the stick with the Team format btw.

Team Persona (I could see Bird leaving though. If so, Persona could borrow someone from Pendragon or an all new character).

*Team Protagonist (If Bird does leave, he would be on a different team of course).

Team Zooganic (They are one of the 3 major rivals for Persona in X and King is even getting a UX).

Team Yggdrasil (Same reasoning as Zooganic for these guys).

*Team Pendragon (An even bigger hypothetical than Team Protagonist. This firstly assumes they don't dissolve by the end of X, which I could see since their leader has been acting crazy. Second, this assumes that either Team Persona does not borrow a member from them, or if they do they can get an all new character).

Beyond this there would obviously be plenty of new characters, enough for an all new team or two.

While a new Blade system really isn't necessary, I can't lie, I need TT to bring back a Zero-G esque fusion system so we can get the return of Samurai Ifrit, using the existing Samurai and Hells motifs (Also would mean that Tenka would get to return in a major role after her current disappearance from the narrative. Plus, having the average battle include 4 people would be a good opportunity to give more characters screentime).

I speculate (and wholeheartedly believe) that the upcoming Phoenix will kick off the 90 height ratchets with 9-90.

The reason here is that Phoenix has a ratchet pattern.

Phoenix Wing came with 9-60
Phoenix Rudder has 9-70
Phoenix Flare comes with 9-80

So in those terms...
Phoenix _____ will come with 9-90

(The whole batch of underscores is just filler for whatever the next one might be)

In other regards, we might also see a 9-100 with a BXE (BX Expansion) release for Phoenix, while UXE (UX Expansion) Phoenix won't have a ratchet
