According to a Polish retailer, a PS3 will be coming to Europe on September 28th, just a few days after TGS 2012 ends in Tokyo, Japan. According to Polish site Polygamia.pl there will be a 12GB SSD PS3 which will retail for €199 and it will be joined by a bigger 500GB PS3 model which will cost €299.
However, this is the first time a 12GB console has been mentioned. Previous rumors pointed toa 16GB SSD version, though they could be one and the same (the missing 4GB could be used for system storage and caching). For now, take this as a rumor. Expect something official announced to be at Tokyo Game Show.
