Kingdom Hearts II sora having two hearts

does anyone else here think that sora could possibly have two hearts....nomura said in another report that the fact that he could duel wield was significant...maybe the reason he can have two keyblades is because he has two strong hearts (possibly vens heart)

furthermore i believe that vens loss of heart and soul in sora plus soras body were the makings of roxas and that Xion is simply kairis soul with no body to copy her body i think is built from memories (acronym: No I) from when she left soras body....and namine was created when kairi *died* i guess you can say on destiny islands and since her heart technicly left her body when it went to sora namine was the product of kairis body and soul

anyone got anything they might want to change are add to this

 

i don't think sora has 2 hearts, because roxas could duel wield and he had no heart at all.

 

roxas can duel wield because sora could mostly everthing sora can do roxas can just by the fact he is part of sora
