Hasbro and Paramount have announced a deal in which Paramount Home Entertainment will distribute OAVs that Hasbro will produce.  Among properties on which Hasbro will base the OAVs are G.I. Joe, Transformers, and Duel Masters.  The first releases include G.I. Joe: Valor vs. Venom in September, and Transformers Energon in October.  Hasbro will release OAVs based on other properties next spring. 
These are clearly distinct from the existing material based on these properties.  The Duel Masters anime, for example, is a ShoPro production currently airing on the Cartoon Network (see 'Duel Masters Anime on Cartoon Network in March').
