Math Gran Prix bought by Humongous

Atari's assets were sold *again* and on this page they list who bought what.  Most of it relates to newer titles and franchises, but a company named "Humongous" bought Math Gran Prix.  Has Atari even done anything with that title since the 2600?  I can't find anything on it.
