Maxis has redesigned the official site to match the new logo. That logo was introduced around the E3 and has been spotted on several movies and screenshots before. The new site has a slightly different look, though the place of all content and the content itself are still the same. A new fansite pack has also been uploaded, which you can download from the fansites page. You can start staring at the new design on the fresh Sims 2 homepage.
