SH Figuarts have released the full details for their Star Wars Return of the Jedi Throne Room set, featuring an Emperor Palpatine, Throne and two Royal Guards.
The main figure of the set is of course Palpatine who has lower leg options to either be standing or to be seated on his throne. With no soft goods in play the legs won't have any significant articulation. Palpatine also has his cane and clip on force lightning effect pieces.
It looks like three head/face options are included - neutral, smiling and angry.
Palpatine is guarded by two of the red Royal Guards. These look like they will be static SH Figuarts Zero One figures - which makes sense considering their robes and helmet. They will each have a force pike accessory.
The set is down for a June 2020 release.
