There are rumours doing the rounds at the moment of a Spore expansion coming soon.  There was information leaked onto 2 US retailers web sites (Amazon and Gamestop) that was pulled pretty quickly after.  The expansion is supposedly titled "Cute & Creepy Parts Pack", and had a release date of the 18th of November, so that'd mean pretty soon then.

Not surprising really given that now would be a good time to get an expansion out there ready for those fat Christmas sales.  The price was put at being around $US20, so that'd equate to being about $30 in the Aussie dollar.
