I posted a link last night to a news article that samsung reps were going to some stores in the San Fran area ATT and Sprint and removing the Note 7 displays and signs. I hope they don't discontinue it, and I don't think they will totally. I could see replacement units in other countries and eventually in North America go out, but they might not sell more of them. I wonder if that would make it a collectors item then? Doubtful but that is a hunch I got. Either way even if it comes back if sales are bad good luck getting priority for updates then. That is partially why I jumped to the Edge today. IMO at this point samsung should pimp the Edge with Christmas coming up as the flagship until March, April when the Edge 8 comes out. The Note 7 image will soon be ruined if it's not re-launched.
Now if Apple has the same problem with the Iphone 7 for example they would really have no choice as they only have one current flagship device and nothing to fall back on like the Edge.
