CNews.ru believes that Apple will be launching iTunes Russia on April 21st 2008.
The evidence first came from billboards appearing in Moscow on Friday, with the words 'iSkoro 21.04.2008 (iSoon 21.04.2008) .
Further evidence is from two domains registered: iMacintosh.ru and itunes-store.ru which redirect to a splash page that says "iTunes Store Russia 21.04.2008." The domains appear to be registered by Apple IMC Limited, "the leading distributor of Apple products in Russia."
