I'm now 76 years old. I may not live long enough to see Dragon Quest VI unless someone takes action soon"
I did a quick internet search of her name and location and found her obituary. She died January 3rd of this year. Dragon Quest VI comes out February 14th, 2011. She waited 15 years and.... Kinda tragic.
Her obituary which can be found at http://obits.dignitymemorial.com/dignity-memorial/obituary-print.aspx?n=Edith-Jeter&lc=2629&pid=147602253&mid=4501742 says,
Edith enjoyed reading, playing video games, and was an author of a family genealogy book that she proudly distributed to her family.

Apparently they were talking about Edith Jeter over at Earthbound Central as well: http://earthboundcentral.com/2010/12/earthbounds-translation-cost-50000/
Edith lives on in the SNES RPG community.
