Blender 2.8x is being dubbed “Workflow” by the Blender Foundation, and 2D animators are included in that. The 3D suite has included a tool, called “Grease Pencil”, for quite some time now, and its purpose was mostly to write notes. Since then, people have been using it for modeling (especially curves) and even 2D animation, which led the Blender Foundation to build it up in that direction.
This could potentially bring Blender more competitive with existing 2D animation software, like Animate CC (the Adobe re-brand of Flash Professional) and other tools. Being a 3D-centric application, it has a lot of interesting features to add to the mix, especially in terms of camera movement. (Animate CC just received a virtual camera in the most recent major version.) It will be interesting to see how comfortable they can make it for novices, because this is one of those areas that there’s not a lot of good free software for learners. (Digital Video and Studio Ghibli released OpenToonz, but it seems… more than a little difficult for newcomers from what I’ve seen.)
Blender 2.8 is supposedly aiming for a SIGGRAPH preview, which starts on July 30th.
