Not the point. The point is, if they're going to scrap our guardians then they need to divulge that so people can decide whether or not to keep investing in their characters

It's exactly the point. That information will come out when the game is announced and more details are released. You literally are not going to get any information from bungie about it until after the game itself is actually announced. Don't expect anything until after E3 next year. And your guardians and progress won't be scrapped. You will always be able to use them just fine in the current destiny game.
