Not that has been announced. But then, fans have been animating them and putting them up on youtube for awhile. Some, which were basically done for free, are better than we saw on The Invasion. It seems to me it would be a good idea for 2 Entertain to get ahold of the people who did those animations, throw a few dollars their way, and have the ability to release the rest of the stories.
My understanding is that the cost of animating the two Invasion episodes was already allocated and it was extremely expensive. I'm sure there are others with far more information than I have.
