When is sonic RPG eps 9 come out

The trailer says it'll come out March 2013. They could be more specific like
March the... 2013 and so on. 2 or 3 years have passed and they still didn't make it!

[SPOILER WARNING] do not go on if you hate spoilers.
The game will include: Hyper Sonic, Full Power Seelkadoom, not sure about cutscenes, openings and ending, it is also the final chapter.

My opinion is Sonic AND shadow should've fused into Shadic an beaten Seelkadoom.

I hope this helped! :)
