I hope they say, Destiny 2 is the game you will be playing for the next 8 years. Don't expect a Destiny 3, expansions will keep pushing this game forward and driving the story releasing new playable spaces. Yes that means weapons will be useless after each expansion but they could have a transmog place for armor and weapons looks if people are really that sentimental. I hope Destiny 2 is pretty much what they did for Final Fantasy as a Realm Reborn.
