Speculation for future releases
BX-32: The 3-Player Stadium That was Previously Showcased
BX-33: Weiss Tiger (Already Confirmed)
BX-34: Teased Left Spin Beyblade*
UX-06: Hells Evolution**
UX-07: Team Pendragon Themed Deck Set w/ Drake Evolution**
*: I don't think this will be the highly speculated Drake evolution just yet. This theory hinges on the idea that Chrome is the final antagonist, and they usually get their Beyblades closer to the end of the series. As far as we know we at least have June, July, August, and September, which the other months having more interesting opportunities for a final antagonist Beyblade. Also, this left-spin Beyblade is a BX release, and the Drake evolution should definitely be UX, right? As for what this Beyblade is I'm not sure, but I do like ilinnuc's theory of this belonging to a new 3rd member of Team Pendragon (since they're missing one).
**: As mentioned previously, if Drake is the final antagonist Beyblade, is should release later into the series (this would be 13 months after its launch) and be UX, so this works well. I put it in the Deck set because knew Beyblades has debuted here before, based on my previous theory Team Pendragon should have 3 other members to take Beyblades from, and it opens up space for Bird. Now, it's been quite clear that the writers are building up to Bird eventually having a breakthrough (even though he's currently 49-0). Given how long its been this will probably be at the tail end of the series, and when it does happen, giving him a new Beyblade would make sense. Two UX releases for the same motif would be a first, but Bird is the protagonist after all.
I excluded two random boosters because there is nothing pointing to what they could be at this point. Also, random boosters tend to have pretty random, inconsequential releases (at least compared to the big headliners).
