These pics were taken by Game_Watch at the recent Tokyo Game Show, and shared by MarkMan. They appear to show a new arcade stick that’s being produced directly from Sanwa and the working name is “Sanwa Seiki Receipt Expression”, or “Hope” (?) depending on which translator tool you use.
The model on show is for PS3, has 8 button storage slots + 2 plugs, a spare joystick storage slot, and 2 spare balltop slots. It also has built in LED’s to illuminate the face buttons, 2 key-locks for the case, and a carry handle.
I couldn’t find any mention of a release date, price, or region availability. The case looks like it’s made of very thick plastic, but that’s just speculation on my part.
