Currently, no one but SEGA and Sonic team knows, but I hope that it will be the 20th anniversary game for 2011.
No the Sonic Adventure series ended in 2002 with the release of Sonic Adventure 2: Battle for Gamecube. There have been numerous rumors of a third Sonic Adventure being released but nothing has been released by SEGA to confirm them.
There is a Sonic Adventure #1 and a Sonic Adventure #2.There is now a Sonic Adventure 3 - released in 2011 - the year of the Sonic 20th anniversary.
there is sonic adventure 3
Sonic Adventure 3 has not been anounced
No there isn't a Sonic Adventure 3, there should be though the Sonic Adventures were good games. there is kinda sonic unleashed or in japan sonic world adventure is supposed to be the third instalment in the sonic adventure series
No. The last Sonic Adventure was Adventure 2 which was released in 2001. I doubt there will be another Sonic Adventure but in a interview a member at Sega he likes the idea of remaking Adventure 1.
sonic unleashed was intended to be sonic adventure 3 before the name changed.
sonic adventure 3 is not for ps2 nor not out yet.
technically no but sonic heroes is continuing on from adventure 2
Technically, Sonic Unleashed is sort of Adventure 3; in Japan it is called Sonic World Adventure. Aside from that, it is not really clear if there's going to be one.
1:Sonic the Hedgehog 2 2:Sonic Adventure DX 3:Sonic Advance 2 4:Sonic 3 & Knuckles 5:Sonic the Hedgehog 5: Sonic the Hedgehog 4: Sonic Advance 3 3: Sonic Adventure 2: Sonic & knuckles 1: Sonic CD 5: Sonic the Hedgehog 3 4: Sonic the Hedgehog 3: Sonic the Hedgehog (2006) 2: Sonic and the Secret Rings 1: (what? not sonic cd?) Sonic Adventure
So far no but sonic unleashed was going to be named sonic adventure 3 but they scrapped that name for some reason.
