The next installment in the Sonic the Hedgehog franchise and more are coming Nintendo's platforms.
Sega has announced that it will release the next installment in its Sonic the Hedgehog franchise for the GameCube. According to a representative from Sega of America, the game will be a brand-new addition to the franchise instead of a remake of the original Sonic Adventure for the Dreamcast, as was first suspected. In addition, Sega is also developing Sonic Mega Collection for the GameCube and Sonic Advance 2 for the Game Boy Advance.
"Building upon the excellent worldwide sales and incredible success of Sonic Adventure 2 Battle and Sonic Advance, Sega is determined to develop and release new titles in the Sonic the Hedgehog series that will appeal to the growing audience of gamers worldwide," said Tetsu Kayama, chief operating officer, Sega Corporation.
While no details on the games have been disclosed, Sonic Advance and Sonic Mega Collection are expected for a release within this year in Japan. Both games will also be showcased at the upcoming World Hobby Fair held later this month in Japan.
Sonic Team also announced that Sonic Adventure 2 Battle for the GameCube and Sonic Advance for the Game Boy Advance have shipped 1 million copies each worldwide.
