I know that most of our fellow collectors would rather like to get him on 1/3 or 1/4 scales but I would be really impressed if Prime 1 decides to make one in 1/2 to match those already confirmed(Batman, Superman, WW)...and a Flash would kill it!
I'm thinking it will be 1/3. Most of their movie pieces fall into this category. The DC trinity is probably one of the few 1/2 exceptions. Seems like only the all time most popular characters will receive that treatment.
I am planning to display these on a custom exhibitor, behind glass, like the one I am currently using for my Mark 7. These will make them look impressive.
