I think I'm not throwing any spoilers - because I just noticed it in the in-game calendar - so it is already public accessible:
It's looks like from 17th april starts a new TFO with some nicely named Universal Console account unlock as reward (Priors World Elite Defence Satellite), and... C-Store Coupon for 100% Discount on T6 ship of our choice. The Event will be 20 days (going by calendar), so it will propably be 14 token Event Reputation project.
Ok - it's shows from 17th April on calendar, but in the description it states Start: 18 April.
And the coupon… looks like it will be earned over more Featured TFO Events... but still - it is free top tier ship, so I'm ok with it.
