On some regions, we rely on distributing partners due to the different market conditions and regional differences. For big launches, such as Siptah and 2.4.4, getting the preparations ready (and all that involves) may take a bit longer.
That being said, we do everything that is in our hands to make that wait as short as possible. Conan Outcasts released Siptah in the Japanese regions today, and we hope to get this content to the remaining Asian regions as soon as it’s possible.
