Due to technical difficulties I won’t be posting the pic I took at Toys R Us, but yes, Star Trek Kre-O sets have been sighted. I found a few of the sets earlier(but not all of them). These sets come with parts that light up as their main gimmick.
Not sure when other retailers will begin to put these out, but Toys R Us is your best bet if you can’t wait any longer. Happy hunting!
