These will never replace the need for regular colonoscopy. If a pollup is imaged, a regular colonoscopy will still be required to remove it (regular colonoscopy has a tool built on the cable to do this).
I had the capsule endoscopy done twice and it worked like a charm both times. It has (or should) completely eliminate the crude procedure known as "upper gi series" which I also had and which is a nightmare!
Cheers.
