Hmv art is better for sure. There will be at least 2 WWAs (France have 2 listed already), possibly even be a 3rd.
It wouldn't be first time that happened, but I doubt they'll milk Black Adam quite like they did The Batman. Even though Black Adam is good, there's a huge gap in popularity between them.They may follow the trend of The Batman. Use the worst art for the first Best Buy steelbook then release the better European steelbooks at Best Buy later.
