    ... will always will be English centric ...  

I don't think you can claim that. Maybe for the next few decades or centuries but beyond that who knows what will happen.

    Practically every tome, text, blog or article of any
    real value in the field is published in English ...  

Is it possible that you just don't know they exist? You probably don't know enough to make such claims, as an English speaker myself, I know of a few books that I would want to read but they haven't been translated yet. There aren't many, but then again I don't know about others because of me not knowing the language.
