which ppv will cena drop the title?

[hbkizbest]

Dont you think it would make sense for him to retain at summerslam so he can have his 1 year reign, and then do drop it at unforgiven. Summerslam is one of the big four ppv's so it is more likely he will lose it at summerslam.
What do you guys think?
