The images of the H 101 - P 25 for Hasselblad H1 are early design models, you can now find images of all four versions of the P 25 here:

We are constantly updating our web site and press material, to be able to answer customer and press curiosity and enquiries, so look out for the new datasheets and images in the near future.
The answer the questions raised here about the water/weather proof ness of the P 25's I can start with stating that all the four models have the same resistance or non resistance to water, snow or dust.
The P 25 for Hasselblad V, Mamiya 645AFD and Contax 645 all have the same exterior from the front plate and backwards, whereas the H 101 - P 25 for Hasselblad H1 differs and its designed to exactly match the colors and lines of the H1.
When we are talking about bringing the equipment outside or in a misty environment you should have no problems operating the equipment unless its pouring down with water.
The Phase One P-backs are designed to fit the medium format cameras and these also does not have specific weather condition protection.
When the Mamiya, Contax, or Hasselblad P-backs are operated in a wet environment with water pouring down, or in a very dusty environment, say a sandstorm or similar, precautions has to be taken to ovoid damaging the equipment.
In general the P-back can however withstand slight rain drops, snow or misty weather, and if the CF-port gate is not opened dust and water is not very likely to get into the interior of the backs unless it is heavily exposed to water or dust.
