We may or may not find out for another couple of weeks for various reasons...
With Danan being in-and-out for the next few weeks, I did catch the relatively huge DLC download Friday... it's most likely for the upcoming Skybox and events for at least next week maybe two...
If anything, all they announced on July 1st last year were the Loyalty tiers with the rewards coming a bit later... maybe this year they'll announce the tiers and actual rewards at the same time so people can decide if it's worth it or not...
