To commemorate the 40th Anniversary of Return Of The Jedi, Disney will be releasing a new Exclusive Droid Factory R2-S4M Droid, who can be seen in the Movie as Jabba’s Bartender.
Shop Disney Japan has already created a product page for this Droid and it is listed as coming soon. You should expect this to go up for sale soon at ShopDisney.com and at Disney Parks as well. Possibly for May the 4th? If we see it go up for sale or receive more details, we will be sure to make a post.
