A promise is defined as a declaration of assurance, a claim of what will happen, to give good ground for expectation; I'd say a dev post saying something will happen is plenty good grounds to expect it. The word "promise" itself is not required for something to be a promise.
Why are you always doing this anyway? whenever someone tries to hold CCP to their word you have to swoop in and find loop holes.
I remember when you even claimed weapons, vehicle, and dropsuit racial variants were NEVER promised within 1 yr from Fanfest despite you yourself having been there. I had to link you the talk (Advancing the core) where they said they'll be out within 6 to 12 months of the time of that Fanfest. Speaking of which, I'm actually hopeful and optimistic that they will be able to keep that promise.
