If you look at the Wikidata class browser [1] there are ~ 300 classes with
more than 1K instances so there is definitely a long tail in Wikidata.

Other than that, the next DBpedia release will feature two new datasets
(DBTax and Hypernyms) that extend the type statements beyond the DBpedia
ontology.
Although these will probably not be included in the main dataset (SPARQL /
LinkedData), will be offered for download.

Best,
Dimitris
