Gaming website Kiziko claims that we wont have to wait long till the announcement of the next big Sonic title.
“Kikizo can reveal that Next-Gen Sonic is scheduled to be announced at the end of this week, on September 9, before making an appearance at the Tokyo Game Show, which starts September 16.”
Apparently, the game will appear on a variety of next-gen consoles and will be based on the demo shown earlier this year at E3.
