Hollywood Reporter:

Nearly a year after moving his overall deal from AMC to Amazon Studios, The Walking Dead creator Robert Kirkman has lined up his first new series under the pact and it's a familiar one.Amazon Studios has handed out a straight-to-series order for an hourlong animated take on Invincible, based on Kirkman's recently concluded comic book of the same name.
Of note - the Seth Rogen/Evan Goldberg written and produced film version is still progressing.

Interesting to see an hour long animated series coming from Amazon.
