Eventulion

Don't YOU Eventulion ME.

Eventulion is when the creators promise their audience anything soon although it's obvious this promise will inevitably be broken. This also refers to when plans for some upcoming feature, installation, or update that keeps getting pushed back for any reason.

Eventulion can be used as a verb ("Nintendo Eventulion'd us hard last fall when they promised us Super Mario 65.") or a noun ("Illumination gave its audience an Eventulion when they said the next seven Despicable Me movies were coming out in the upcoming month.").
