Well, after doing several more days of research I've eliminated the EOS 7D from my list. The main reasons are:
-Audio gain trouble
-The camera only records up to 4GB per clip (bad for events like weddings and parties)
-The card format it uses (Compact Flash) is incredibly expensive and can't hold that much video (the average clip size is 12 minutes, and 12 minutes is the 4GB maximum a CF card can handle)
-Lenses and filters are also incredibly expensive, and are necessary in order to make the video look as nice as Philip Bloom's (although his incredible talent also helped him out with that!) stunning films
-It only records to .MOV, which isn't bad when you use a Mac, but if you're a person who uses both Mac and Windows, it presents a few issues.
So, while it's a great looking camera, it's just not the right one for me. I started doing more research on the HF S10, and found a ton of stunningly beautiful videos filmed with it. It really showed me that if the person knows what they're doing and possesses the talent, you can do absolutely amazing things with it. I think true talent can be identified by a person getting around a camera's lack of professional features, and making it all work anyway. And if you know what you're doing with things like manual focus, white balance, iris control etc., then you can create some pretty awesome looking shots.
Pretty much the only thing that bothers me about the HF S10 is the fact that it's low light performance isn't the greatest, but it certainly isn't bad either. Videos showing its low light capabilities were better than that of the Panasonic AG-HMC40, which costs $1200 more than the HF S200 will. However, I'm not going to be doing a lot of low-light shots, so this isn't a big deal. And if I need to, I can just add lights and then do some digital work and darken areas with a mask or whatever. There's always a way to get around something.
Thank you to all who helped me out with my decision. You provided excellent information to each of my questions, and helped me learn something new about the art of digital film making. I can't wait to get my hands on the HF S200 when it comes out.
