Machinarium will finally come to PS3 in September, at least in Europe, according to ... a comment thread on a European PlayStation Blog post. SCEE's Ross McGrath teased " two new titles as well in September, one brand new and one new to PSN" in a PlayStation Plus post.
Reader Antares commented on that post guessing that the brand new game was Double Dragon Neon and the new-to-PSN game was Machinarium, to which McGrath replied "Give the man a cookie, he's 100% right!" Community journalism!
The PS3 release is supposed to be tht "ultimate" version of the adventure game. Recently, designer Jakub Dvorsky indicated his interest in porting the game to Vita as well.
