Well... There's two sides to a coin. English version MUST be released in September because of Risen in October (obviously), but then... Well, you know how successfull pirates works in Russia? :P If english version will be released first - they will made quick-translation (pretty bad and sucky) and release it. That dramatically will lower sales in Russia.

But yeah, you're right, that was juts mine opinion about which version will be released first.
