No, it’s not been announced. However, Gizmodo caught up with a Canon rep at PMA and had the following to say regarding the 5D:
Interesting bit just tossed our way by the Canon rep when we asked about a 5D follow-up, slightly paraphrased: The EOS-1Ds line (their full-frame pro DSLRs) is on a three-year upgrade cycle. The 1Ds Mark II came out in 2004, and the Mark III dropped in 2007. The EOS 5D came out in 2005.
Right, it’s cryptic and all, but that’s got use thinking Photokina, eh? The 5D arrived in August ’05, so we should be looking toward August ’08 on the 3-year upgrade cycle? Nice catch Giz.
For more info, stay tuned to the Canon 5D Mark II page.

In recent years, the demand for digital SLR cameras featuring high resolution and wide graduation ranges capable of capturing every detail of the subject matter has continued to increase, particularly among high-end amateur users. Additionally, the increasing user requirement to shoot from the same focal length and angle as 35mm film cameras using interchangeable lenses has led to significant interest in the development of 35mm, full size CMOS image sensors. 
Tokyo – Nikon Corporation is pleased to announce the introduction of the high-performance PC-E NIKKOR 24mm f/3.5D ED, PC (Perspective Control) lens. This new lens is equipped with a tilt/shift mechanism that gives photographers the flexibility to manipulate image perspective, distortion and focus.
An ultra-compact Silent Wave Motor (SWM) built into the lens body ensures fast, quiet and accurate autofocus operation and complements the compact, lightweight design for superb handling. With dimensions of only Ø72 x 85 mm/Ø2.8 x 3.4 in., this new lens is ideal for general photography and perfectly suited for many who specialize in travel and nature photography. 
This new Micro lens allows photographers to shoot 1:1 life-size close-ups without the need for additional accessories. To ensure superior picture quality at all subject distances from macro to infinity, a host of state-of-the-art, Nikon original optical features and technologies are incorporated. Internal Focusing (IF) design allows faster, smoother autofocusing. Two aspherical lenses are employed to correct spherical aberration and coma. The incorporation of a Nikon’s exclusive Nano Crystal Coat dramatically reduces ghosting and flare caused by internal reflections. An additional ED glass element minimizes chromatic aberration to deliver higher resolution, high-contrast images. All of these factors contribute to the extremely accurate image reproduction capability of the AF-S Micro NIKKOR 60mm f/2.8G ED.
