As for now, no spanish publisher has announced anything. I wouldn't have high hopes that it is translated in the future: Nosolorol still struggles with releasing the original game (it hasn't stopped publishing, but would make no sense to now stop the original game line and get back to re-start with the 5e mechanics).
Devir is lately publishing most of Free League's products, but I don't think it makes sense for them to focus on Symbaroum, as they have already some fantasy games out and RoS would overlap with their other products.
