Needed to do some quick tests with the 7D today- Terra stepped in to help out with really no notice at all and after treated me to a quick dinner! How awesome is that? She wouldnt even let me pay! She’s been a HUGE help with modeling for various projects.
Im very pleased with the 7D, there are a few little things I am noticing, so example, it may be more sensitive to green light that the 5Dii. That aside, the focusing was absolutely better, I just cant believe how much its improved. In the past, Ive been very happy with my 5DII, but Im wondering now if its a little on the pink side? Posts to come shortly! 
"The 7D support is very preliminary. We are often able to provide preliminary support for raw files from new camera models. Camera Raw and Lightroom will open and edit these files, but profiling and testing is not complete. It is likely that some processing aspects will change somewhat when we provide final, official support." -Adobe Support
Interesting- Ive tried to open them with Adobe Camera Raw and Lightroom, they arent being recognized. Im wondering if Canon means after using their software to convert to a DNG or Tiff.
"Note that ACR 5.5 and LR 2.5 can open Canon 7D CR2 files. Not sure if this version of ACR secretly supports this new camera model but the files open never the less. The DNG 5.5 Convertor also recognizes the 7D CR2 files."
Was all else I got on it so far…
Also found in the ARC update media release they mention something to the effect of dealing with green response on those sensors?

Brian- You were right- ACR 5.5 supports the Canon 7D!!
You mentioned that 5D seems a little on the pink side.. Well I seem to be experiencing the pinkness in my shots as well… Is there any way to fix this? Its very time consuming trying to adjust the pinkness out.
