err if i remember Sasuke said he would obtain power his own way not the Mangekyou =/ and also to not be like Itachi's puppet so i'm thinking he doesnt want the Mangekyou nemore since Itachi wants Sasuke to get the Mangekyou....this being proven when Itachi murders the clan and says "You can obtain the same eyes as me...and once you do come and confront me".So i'm guessing Sasuke will develope either a new Sharingan or just improve the Chidori or something and use it with the normal Sharingan =/
