Jiraiya and Pein aren't characters who talk about their strengths, weaknesses, abilities etc. If i remember correctly we didn't learn anything important about the Byakugan or the Sharingan until long after they were first introduced. In the case of the sharingan we didn't learn much of its abilities until the 'epic' Naruto vs Sasuke battle, and I still can't tell you exactly what its abilities are, it seems like every time we see a Sharingan user they have some incredible new ability.
What I was trying to say was that Pein isn't much of a talker so I don't expect him to say much about himself, but I would expect that at the end of this battle we would get a nice little summary of "some" of his abilities as is the norm in Naruto, although I believe it will never be fully explained until he is finally defeated, even so it would still be one those "?" cases similar to Orochimaru, Hidan, and Kakuzu.
