As far as i know there should only be the old style (like urs) and new style (the huge looking one)... What's a V3?
EDIT: As far as your question goes... i've heard XXXs like BIGGG boxes, so do maybe around 6-7 cu ft sealed? It might just be in the small side though...

They do well in monstrous sealed boxes. 8cubes or more if you have it, if not, they still perform in more normal sizes.
