Windows Phone 8.1 update

Hi everybody,

I've got a windows phone (Lumia 820) and am really happy with it, I really like the OS and everything but I would like to know when will the windows 8.1 update be available in my country. I live in Mauritius in the Indian ocean. I know that there is only the beta/developer version available but when is the stable version coming out, at least in my region??

Thanks.
