Lightroom and Camera Raw / Bridge gives a crop on all raw pictures from Fuji X-E1 at import. This happens when shooting only raw, but not when shooting raw+jpg. This is a known problem that neest to be fixed ASAP.
Historically, we've done releases every ~3 months or so, and the last release was in December, so that should give you an idea of when the next one will likely be.
Frankly, I think you're overstating the issue by claiming that CS6 is "unable to process" the images. CS6 can process them fine. It's just that the initial crop is wrong. You can fix that by selecting the Crop tool and choosing Clear Crop (or press the Delete key). If you have a bunch of images to work on, just select all of them in the ACR filmstrip, and do this Clear Crop step once. This will sync the changes across all of the images.
