I take JCL as comparison to this release. JCL first week sale was 122, 820 but with no promotion and natural conflict in Japan in that time. But with this GGS, I think this is the first time that Kara promoted the song before the release date. So I might guess the first week release will be really huge, exceeding the 200K mark.
My prediction: 90K first day, 205K first week.
