There's an important difference in 32 bit vs. 16 bit images (as applies to PS): A 32 bit HDR uses 32 bit floating point numbers for each colour channel, 16 and 8 bit image formats use integers. That has a huge impact on available dynamic range, HDR formats trade practically unlimited DR for precision. It's not just "2^16 vs 2^32 colours".

I happen to agree with you that the compositing of the High Range step of the image and tonemapping should be separate considerations and given separate terminology. Unfortunately that is not a definition that has fallen into common parlance and as such HDR is to most photographers a synonym for (frequently garish) tonemapping. In adobe's way of thinking, ...

I would say the new Olympus OM-D EM-5 Mark II. It is fully weather sealed, and you can get the PRO weathersealed lenses for it too. It does everything that you would expect, including in camera HDR and bracketing. Though I don't understand your flooding issue with the AW1, you're asking rugged, not waterproof. For the Olympus cameras you can get underwater ...

You should choose a higher dynamic range (e.g. 32 vs 16 vs 8 bit) to maintain smooth variation in data. When you come to downsampling the data, you have control over how the values are filtered. For photos, this generally means gradients. If you compress the data into 8 bits, there generally won't be enough "steps" in channel values to smoothly combine the ...
