Ok..here is a little news update :
Japanese sonic cd music will be able to listen on in sonic gems collection. It will be in the sonic museum in the extra stuff on sonic gems collection.
Yojiro Ogawa from sonicteam and sega says in an pressinerwie that Knuckles chaotix(one of the forgotten games),segasonic the hedgehog(i wonder how whit the rollcontrol), nights into dreams(So cool game) and burning ranger(WOOHOO) will be in a sonic collection if sonic gems is selling good.
The e3 video for sonic the hedgehog next gen was not a game related video. It was just a movie created by Yuji Naka and what he expects of a sonic game in the future.
Those news are real. not fake.
