In a video about the new comic the new figures are seen at 3:21
Jon is taller than Damian but I think he's too tall. I don't think he looks like a nine year old. The eyes need some work.
This is probably the best Damian figure that's ever been made. I can't tell for sure if the neck detail is right though. Toyfair isn't far away so I'm looking forward to more pictures.
