In 2012, the NGUI programmer stated that NGUI was making him three times what his previous job had paid, and that his starter kits were making $700-1500 a month. http://www.tasharen.com/forum/index.php?topic=2126.0

So that suggests there's certainly some revenue there.

NGUI was also one of the most successful plugins in the entire Store, so his revenue, while significant, should also be treated as a ceiling on what a company can expect to get.

There certainly is, but i doubt its anywhere close to their license fee related revenues.
