>>5783749The only true official info I can see is 9/25 release.
FYI
ジョイント使用数:全20個 --- 20 total joints used
・4mmジョイント×3個
・6mmジョイント×4個
・6mmダブルジョイント(15連結)×1 -- 6mm double joints (15 in connection)
・8mmEXS(※EXとシングル)×12個 ---8mm EX and Single
So I think the EX is the ones with the holes for regular 8mm to plug into. And this 15 connected 6mm joints, is using the regular 6mm joint parts but keep connecting the middle piece. Interesting joint usage.
