I agree. Who says that Batman, Superman, GL, WW, etc... are supposed to be posed together?? Sure you can if you want. But Batman defiantly has his own set of villains to be set up with. GL will have his. I am sure there will be Superman villains also. Those who come down on the action pose of GL, well I feel that If GL and or batman were both true 1/4 scale they would look great displayed together. It's not like they are all on the same base. If they were the action pose would be off. But I think they are putting these characters in poses that best represents them. Batman, Superman, and Wonder Woman can be in classic museum type poses. It fits their characters. GL and Flash have to be in action type poses IMO. Museum for those two would be sort of boring. They just are not as iconic. You got to show off GL ring for goodness sakes. I don't know what the hell you do for aqua man
. But The fact Batman is too big and GL is too small is because you have different artist working on them and the make them as they want. Since SSC was not calling any of these the JL collection I don't think they were going for a unified look.
I am sure SSC will be making another GL. I would just not plan on seeing a larger GL anytime soon. In fact I would not be surprised to see SSC starting a JL comiquette collection before they ever make another GL PF.
Of course this is all just guess work on my part also.
