In regards to leaked animatrics, how should we regard them in terms of continuity?

[PhantomInfinite 2]

 So we've seen some leaked animatrics regarding EQG and the show and I was wondering, how should we deal with them continuity wise? Should we treat the events that have happened in them as things that have already happened or coming soon(like episode title descriptions). For example, if an animatric of spike getting wings was leaked, should we say spike has wings now or he's going to get wings.
