I told you so – you could of guessed it yourself! Shacknews reported that a Spore expansion pack is already in the works according to a slide from a presentation at the GDC. No details were announced, but if you follow the current pattern of expansions, it’ll be released 6 months after Spore. So it is safe to say probably around March or April of 2009 it will hit stores.
