Following the discovery of 5004939 The LEGO Batman Movie Minifigures last week, the other three minifigure packs that'll be available exclusively from Toys R Us have been revealed in a poster found in German TRU Stores.
In Germany each one will be sold for a week or so. If the promotion is anything like past years availability will vary from country-to country. In the USA they will almost certainly be available during the store's traditional Bricktober event.
The other three packs contain City workpeople, Ninjago and... actually I'm not sure what the fourth pack is: a random collection of fairly cool figures which look to be variations of CMFs.
