Yeah, it's been a bit vague on whether Fitbit is going to keep the servers alive, although the article hints towards it. People on /r/Pebble have been working on an open source community store to keep the ecosystem alive.
I thought Pebble really nailed balancing the engineering tradeoffs that go into a smartwatch, but I guess it didn't translate into mass market appeal. It's surprising how quickly things turned after the modest success of the Pebble Time.
