I agree with you that the original maxi head is preferred over the mini head for several reasons, especially when there will be a GT version with more heat generated.
It looks like there is a picture posted out there somewhere on the world wide web, showing not five SBT90.2 emitters, but fourteen (14) SBT90.2 emitters, with 50,000 lumens and 2,000 meters throw mentioned; this as posted on German and Russian and other websites.
Emphasized via repetition:
You know how much I love the Acebeam X65. I fell in love with X65 before it was released. I bought two (2) X65.
Please, please tell me if there is a X65GT coming soon?
Can I send you money now to get an early test sample?
