IDK they're already giving us all those really cool boxes. And this week we got a rifle. From STOWiki it looks like it's gonna be a set to go with our MK XII gear. We shouldn't get greedy and want more. :p
In all seriousness has there been mention of a feature reward? It seems like there has been a shift towards more skinner's box awards rather than time based awards.
Why Jem'Hadar BO? It would be in the tradtion of past FE and we have this new Ketracel-white consumable in the game.
Why Odyssey Class console? Because DStahl say it in the past. "The Odyssey could be a reward of the next FE."
Could be a playable species as a reward, either cardassian or Jem'hadar.
I thin Cardassian would be more likely. There is the thing in the path to 2409 where they said they would give up their fleet if Starfleet protected them. So it would only make sense that if they had any kind of fleet it would be with Starfleet's assistance. So there could be a lot of cross training- transfer opportunities.
