Have you already noticed this selector on our website?
Do you think it simply translates the language of the interface? It does not! It points to a new page (in Russian, right), where one can download not simply a translated into Russian international package of x-cart,(the Russian language pack has already been available recently), but a localization of the software adjusted for specific Russian Market.
Take a look at these screenshots of admin and customer area - "Matreshka's" product details page, adding "Monopoly" to cart and configuring modules, specific for Russia.
The Russian pack includes 3 payment integration modules - Robokassa, Web-money, ASSIST-and 'EMS-russian post' shipping integration.
And, traditionally, 2 large orange buttons =)
