Future of endoscopy nursing?

Hi, I've been a SAHM for over a year now. I've worked ICU/CCU, med/surg, tele. And I've been reading postings about endoscopy nursing and am really interested. I'd like to work in a dr's office but am curious as to what the future is in endo nursing. I've read that patients can now swallow a type of pill that has a camera inside and then bring it to the doctor. If this is the case, won't that decrease the need for endoscopy nurses? Am I out on a limb. I'm just trying to see where the trend is going. thanks for any responses
