Ooh rumor. Take this with a grain of a grain of a grain of a grain of salt to be honest. But the guy who made it said I could share it but wanted to be anonymous.....ok sure
Beyblade Burst is confirmed for a new season (supposedly anyways). The manga will start in April, with the anime starting in March. Unlike Surge it will have 1 main character. They won't have prominently blue hair or anything, but are mostly centered around blue colored things like having blue resonance and such. Their hair with sorta of spike up, but more similar to Aiger in the way that their hair spikes up blue but stays stationary instead of waving around like Hyuga and Hikaru's flames.
Ok now for the products
In April we start of with a booster. Its a knight Beyblade and will belong to the mc (seems believable so far, we get that alot). Next is a random booster. Its a stamina type Beyblade themed around a Hydra. It belongs to the main friend character, like an Arman. Next we have a new stadium. He doesn't have any information on it, which is kinda suspicous considering having info on everything else but I digress. The launcher is a blue long launcher and meant to be paired up with the blue knight. The battle set has slightly different variants of Knight an Hydra bey in a standard stadium with pull launchers.
Next we have our May releases. The first is a booster that houses a defense type bey themed around a turtle. This month also had a knew grip releasing that is supposed fit with the shape of your hand more I believe.
Onto June. Out first booster is a Valtryek, I guess they really wanna play the long con with this guy. He didn't say much about it besides the fact that its like a fusion between Turbo and Brave Valtryek, sure. Out next march release is another attack bey themed around a Dragon type creature, but its not Dragon as in Triumph or Ace.
This is the final month of supposed releases he's willing to tell me so far (Also known as July). It features a Balance type bey that supposed to belong to the main rival of the season. Its a red garuda bird (phoenix like mythical bird) and this time we have more details: Its gimmick it supposed to replicate the talons surrounding by flames snapping at the enemy...ok
Again, please don't take this seriously. Even if he's completely wrong (which he most likely will be) I'll still give you his rumors just for kicks lol.
