Based on the video JND posted about the preorder process, it looks like the statue earns 130 points, which means the price would come out to be $2600. They blurred out the price but not the points.
Assuming that's a real page and not just dummy data, that definitely seems to be on the high end for Superman without the bust (Platinum WW was $3200), but the bust also had a $0 price tag when it was added, so I'm not sure what's happening with the price on this anymore... Guess we'll find out soon enough.
I'm not planning to get this, but the bust on its own would be tempting. Also, it's nice that JND is finally doing a character in a non-standing pose (and Superman is a good one to start with).
