The rumors have been rife about the E-P2. Apparently Olympus China accidentally (?) posted an option for E-P2 on the sidebar menu. There is no leaks on photos yet.... except for a few Photoshop attempts.
On the other hand, some other rumors said that there will not be an E-P2 on 31st Oct. Maybe it will be the E3 successor. Anyway, it is only a couple of days away. Let's wait and see.
