It's really that every comic - book movie becomes part of the
endless cycle of long -
lead trickle publicity: the announcement of the filmmaker; casting
rumors; casting confirmations; first look at costume designs; first set photos;
rumors about plot elements; confirmations of plot elements; first teaser trailer; etc. etc. so that by the time the movie itself actually appears we are sick to death of the thing.
The exact nature of the Nintendo NX is still very much a mystery (except that it exists, and is some kind of a gaming platform), which has
led to nearly
endless number of predictions and
rumors of what it is about.
