According to the Spanish fan site Capital SimCity the Russian web site Absolute Games has SimCity 5 listed to be released in October this year! Furthermore the official distributor of EA Games in Russia SoftClub also states a 2007 release. Since these are only semi-official sources we should take it with a grain of salt, it could just be a misunderstanding or bad communications with EA. Nevertheless no smoke witout a fire and news like these are just what we need in the drought.
