Let's just say the Prelude concept of less functionality in general is a silly idea in my opinion with the exception of those invested folks I mentioned, no matter which camera is in it. Just my opinion of course. Any idea as to how well they are selling?
Jeff - I can't speak with great authority on the video aspects of the Seacam Prelude with the Canon 60D, although I did try it briefly with the whale sharks in Isla Mujares as per http://vimeo.com/28686598.
However, for stills photography, I haven't found a function on the Canon 60D I could not control via the Prelude housing. I don't think the concept is "less functionality", as you've stated, but rather an alternative way to achieve functionality. The camera navigates quite differently than the D7000. I think if you actually spent some time with the 60D and Prelude housing in the water, you'd intuitively see the logic of the controls.
Being a Seacam distributor I'll say no more on the subject, but if you happen to be diving Key Largo anytime in the near future, you are welcome to borrow my 60D and Seacam Prelude housing for a few days and experiment.
