Disney will be releasing a Exclusive Limited Edition Han & Chewbacca Figurine from Solo: A Star Wars Story tomorrow. Price is $149.99 and is limited to 4000 pieces. Per the email I received, you can buy this at your local store tomorrow during their Fan Thursday event which starts at 7pm local time (call your local store to confirm). I assume this will be available at ShopDisney.com as well, while supplies last.
As for the Solo: Die Cast figures, I have received info today stating they are delayed once again and will not be available for sale tomorrow as we were previously told.
