How Naruto Will End or will there be a Naruto Akkippuden

There's been some rumors about how Naruto will end!! One guy predicted that Naruto would accidently kill Sasuke so because he failed to keep his promise to Sakura , he commits suicide I dont know what will happen but i hope that aint it!! Also some rumors about a possible new series, Naruto Akkippuden ,it's suppose to be about Naruto as a Chunin or possibly a Jonin!!
What do you all think?

I think naruto becoming a chunin or jounin is unnecassary he is already at kage level i think by the end of shippuden his going to become hokage. Also there wont be another series it's already been stated by the creator that naruto is reaching it's climax.
