My guy in Hong Kong said the chase Dr. Manhattan was 1:96. These are out in Hong Kong now (he said they got an early release), but not yet in Japan. He only knows about the individual blind boxes, but if there are indeed 3-packs for US distribution (like the Halo 4-packs), I doubt he'd know about that.
I'm tempted to get these now from overseas, but I'd be kicking myself if the much cheaper 3-packs, and 1:4 Dr. Manhattan chases, started appearing stateside.
