Amazon Canada has listed The Sims 3 Plus University Life! The date listed is March 23rd, which happens to be a Saturday, so the date is not one to go by. However, this does mean we are only days or weeks away from an official announcement. 🙂
Thanks Rincon Del Simmer!
*Update* – Amazon Spain has also listed The Sims 3 *Plus*, *Limited* & *Standard* editions of University Life. Thanks Les Sims Wiki!
