"In August 2006, Sakurai and Miyamoto stated that Sega's Sonic the Hedgehog was the most requested third-party character to be included.[25] Around the same period of time, Tips & Tricks reported that Miyamoto has stated Nintendo has actually contacted Sega regarding this, and that they're awaiting a final decision.[26] Then, in the October 2006 issue of Electronic Gaming Monthly, he mentioned that, "Sega's hedgehog would be the perfect addition to Brawl's cast." An article in the first issue of a Swedish Nintendo Magazine named +N makes a report that the known confirmed characters will be in Brawl, along with Sonic the Hedgehog as a playable character,[27] though the magazine's credibility is questioned. Yojiro Ogawa, the director and producer of Sonic and the Secret Rings was asked by the UK's Official Nintendo Magazine about to see Sonic appear in Nintendo's upcoming Super Smash Bros. Brawl and he said: "In my personal opinion, it would be great to have Sonic in it. But that would really involve Sonic and Nintendo's management, it's nothing to do with me!"[28] Yuji Naka, former head of Sonic Team and the chief of PROPE has said that he wants to see Sonic in the next game. When IGN asked in an interview about the upcoming Mario & Sonic at the Olympic Games as to whether or not Sonic would be seen appearing in Super Smash Bros. Brawl, Nintendo Europe marketing director Laurent Fischer stated, "That's not on the cards at the moment."[29] As of June 2007, it is still unknown whether or not Sonic will be included in the final production."
