This is just a theory, but I think that Issei will go into a perfect Juggernaut Drive. I some how keep on having this feeling every time I read about it in the light novel.

Here is the reasons why: (1) When losing Asia in vol. 6, he went into a incomplete Juggernaut Drive. Meaning he had not reach the perfect form. (2) He went beserk after losing Asia and that trigger the form. (3) Base on what I read so far, there seem to be an intention from the other characters to stop Issei if he were to go into the perfect Juggernaut Drive.

It was because of Issei rage that he went into the incomplete form. So let just say that it's possible and Issei does go into the perfect Juggernaut drive. How will it happen? What will be the trigger (somebody) to make Issei go so berserk that he will go into the perfect form?

If that happens (AND I'M NOT SAYING IT WILL), something terrible (or worst) must happen to the one person that loves the most. The one person who he alway does his best for and has always protected. That would be Rias.

Again this just a theory. I can be wrong. but this is what I have been feeling for a while now. Please reply to me of what you think.
