In your original post you never mention first week either you just flat out said it'll only reach 100k.
You were wrong on both Xenoblade and Octopath both comfortably passed 1m.
Come on that's pretty childish =p Ofcourse it was First week, I even got quoted right after by someone saying 'i think it can do 100k FW'
Xenoblade post was about retail, at that time it was at 0.96-0.98 on VGchartz so yeah it took some time to get their. The only thing I give you is that I thought Xenoblade would be more popular than Octopath because of the hype around those two games that I personally felt.
