PES3 comes out on October 17th so almost all of us will find out the squads only then. The summer transfers were only partially done in the PES3 beta version. So the current answer is no. When the game is released they could be done but we don't know yet and if you want someone to guess, ask one of the psychic members.
We have a thread called PES3 QUESTIONS. Use this for er.... Questions on PES3 next time.
