Honestly, I don't think there were ever plans to "Log in every day for a year and get a free burtgang!" deal going on - right now it seems like the system works like, for a lack of better example, a facebook game that rewards you for consecutive logins.

I really hope they don't try and make it so you can "earn" pre-existing rare items through frustrating gambling. I would honestly rather get unique furnishings/costumes than that.
