Hi Jason,
I've been thinking of getting a new camera, and the Fujifilm Finepix S8000fd is one of the cameras I'm considering. I remembered seeing the conclusion of a review of the S8000fd, which preferred it to the Olympus SP-550UZ

Another review really slated the SP-550UZ - I think it preferred the Panasonic TZ18 (another one I'm considering, the general consensus of reviews I've seen seems that it's better than the S8000fd).
I didn't realise there was a SP-560UZ - a quick search shows it's only just come out. When I'll get time, I'll do more internet searching, it could be interesting - it's obviously an improvement on the 550-UZ. Being new it'll obviously be more expensive and the price of the 550-UZ should drop. But the reviews I've seen have definitely put me off the 550-UZ.
Anyway, there are plenty of camera reviews out there on the internet, although they may not focus (no pun intended!) on wildlife photography.
