Pentax may will have their new full frame DSLR camera on display at the CP+ show that starts in Japan next week. I am not sure if any specifications will be officially revealed. Shipping should start after the summer.
In addition to the new lenses, there will be also other new Pentax products announced.
Update: the Pentax full frame K-mount DSLR camera is now officially announced, see this post for more information.
