Hey, unfortunately translations for PRO are not planned currently as they are simply not feasible.
Many offered their help with that but the amount of work which would be needed is easily underastimated as there are over a million lines which would require translation.
In addition, every future content-release would require translation as well, so it would not only delay every content-release but it would also be an ongoing project which would require long-term dedication for many people.
In the future it might be possible with AI but that might also cause many issues.
Greetings~
