Do u think there will b a halo 4?

U kno,i jus though about it,i beat halo 3 on legendary and saw that master cheif is heading towards another planet,but b4 that he says wake me,when u need me.......i think there will be a halo 4 bcuz the developers did say it will be the last halo in the saga...think about it...there will b a new saga,they never said it the last halo game besides halo wars,they finished off the covenant..there is a new force out there......Covenant=old saga,New force=new saga..get it..
