This poster appeared at ToyFair 2020, from Diamond Select Mezco Figures. And....
It's a CG of something they'd like to do, but apparently what they didn't like to do was create CG because...they couldn't choose a photo where the Sonic head wasn't clipping half way through the surface somehow? What's even going on here?
It looks like they want to make a 'nendoroid style' classic Sonic figure where it comes with accessories & has changeable hands/faces for poses and expressions. It looks like it may come in a Genesis game box style box if it gets made.
