It's been a while since we were told about the precursor scavenger hunt that ArenaNet wanted to implement in-game. Last night, with the intention of being as transparent as possible, Colin Johanson has updated the community with its development timeline:
We are however working on expanding reward systems to make them more re-rewarding across all parts of the game, making the open world more rewarding, and adding new ways you can earn precursors as rewards via new reward systems taking advantage of our open persistent world.
Some of these additions will come as early as the January release, and will get covered in more detail in the next week or two as well release all the details about this release once testing has signed off it’s all ready to go in January. (we’ll also provide a high level summary of our goals with reward systems, etc. in our 2013 blog post, which should be out next week) [Source]
No conflicting statements here, as a game designer when they are working on something, usually that means they are designing it, as that is their job.
Good catch and thank you for asking for clarity! [Source]
