According to the page on Mobile-Review, the review was posted on March 30th in Russia, so I am fairly sure we aren't experiencing some kind of April 1st stuff here.
The article predicts a price of 30,000 rubles (which trades currently at about $1,000 USD) in Russia and a release sometime in June. I'm no expert about the cellphone prices in Russia, but I am hoping, along with Rob at Phandroid that we can expect to see the Galaxy S to be significantly cheaper when it gets released in other markets. With HTC's EVO 4G positioned to be the major competitor, price may be the deciding factor in many people's decision.
