Thanks for posting. The Note 3 should be an awesome phone. Personally, I think my Note 2 has been the best phone I've ever owned.
Regarding a release date, Sprint wont have any information at this point. These articles are address the manufacturer (Samsung) release date of the phone. It will then be up to the individual carriers to decide when the release is if they decide to carry it. We have a good relationship with Samsung and I wouldn't be surprised to see it but it's just too early to know anything for sure. As we get closer to a lunch date from Samsung we should start to know more about Sprint picking up the device.
