Yesterday ToysRus.com listed the Forces of Destiny Platinum Edition Princess Leia Organa & R2 as a Exclusive, then some online retailers posted preorders for this item as well. So I reached out to our contact at Hasbro and asked if this was a Exclusive or a Non-Exclusive Product and got the following response
"Product will be available in late 2017/early 2018. They were revealed at HASCON, and are not exclusive."
So these are not Exclusive and was just a listing error on ToysRus.com which has since removed the "Only at Toys R Us" logo from the product. This should clear up any confusion.
