Grendel, exactly!! CIs do not eliminate ASL! It just ADDS another language.
It's exactly like the way Spanish is still widely spoken in Holyoke, even though many if not most Borucia (sp?..meaning Purteo Ricans) can speak English pretty well. Two of my friends are Borucia and they are fluent in both English and Spanish. But simply b/c they speak English, it hasn't turned them into Anglos who are basicly Average American suburbanites.
faire joure, Yes, I have met CI kids who are doing well. They are still pretty much functionally hoh. I think what you're missing is that booth performance really doesn't translate well in the real world. Heck, even LATE DEAFENED people complain that they don't have access to the hearing world. (although with them they have access to the hearing impaired world, rather then the deaf world, since they don't identify with being strongly visual) That should tell you something!! A lot of times a dhh person's speech perception has more to do with how well a hearing person speaks. It's hard to explain exactly......but hearing people who are regularly exposed to dhh folks tend to subconsciously modify their speech, to make it easier for the dhh person to understand.
I remember when I would return to college after month break my friends would have to relearn how to modfify their speech patterns, and when I went to my camp reunions, people who hadn't seen me since I was a teen, had trouble understanding my speech, and I had trouble understanding their speech as well. Bear in mind, that I have pretty good speech, and can access quite a bit of sound with my hearing aids.
I don't know where the dividing line is between hearing and hoh. There are prolly some "almost hearing" kids in the current batch of implantees........but functionally hoh does NOT mean hearing. We can be "almost hearing" I know quite a few born/early hoh people who consider themselves "almost hearing" ....but only time will tell.
After all, the CI doesn't help with accents or noisy listening situtions or people who don't have good speaking abilty. Even the best hearing aids/CIs cannot overcome bad speakers. Those of us who are orally fluent and have a lot of access to speech still say "What?" a lot.
It's like saying that if you're a good driver under perfect conditions, you'll be a good driver in tropical storm or snowy conditions or whatever horrible conditions.
