My guess would be that it is far more likely that we see a Chekov figure as opposed to an Uhura figure. Uhura will require a female body and outfit to be produced while for the most part they could just pop a Chekov head on a Sulu body/outfit and be done. I fear without Nanjin's direct influence over Trek, QMX will go the cheapest route possible.
Indeed. Chekov is basically just a new head sculpt, everything else is re-use. That's about as low risk as it gets from QMX's point of view.
