User blog:AokijiSencho/Chapter number v.s. Episode number

I have been following this page for quite a while now but have only just recently joined up. I have been a OP fan for a while now and  I am thoroughly enjoying both the manga and the anime.

Now I am not sure if what I am about to ask has been asked already but I have so far been unable to find the thread/blog that can answer my question. If there is such a thread/blog, please do diregard this. My question is this:  Right now we are currently at Chapter 721 in the manga and episode 651 in the anime. Am I to assume that there is goign to be a 1 episode per 1 manga ratio? if so does that mean that there will be another 30 episodes of the anime just to catch up to the current manga chapter? let alone to finish the arc?
