As of right now, there are no known major issues. However, some players have indicated they needed to do a license restore after the name change, and some have mentioned their in-game friends/clan list stopped working (but this may be due to another issue...as some who didn’t change psn are also reporting it). This being said...since it is a new concept for PS, I would urge caution to you. If you wanna do it, then by all means do it. Or you can wait for more actual testing to be done since rollout & see if anything major negative comes from it.
