Xenoblade X is slightly higher than what Xenoblade had at the same time before the release.
Bravely Second, recently, fell behind, instead. But still, considering how Square seemingly didn't invest in this sequel as much as we thought at the announcement (and the brief development time - September 2013 to April 2015), a debut slightly behind the original shouldn't be that bad for them. I still want to believe in a better debut though! Penny, my master, teach me the way!
Also, whenever I see the comparison for P&D, I think that, while it'll certainly debut lower than the original, the difference could be not as much as we think. The original P&D was a strange case: a casual aimed title with far more pts than the actual debut (around 500k). This despite the price being low (IIRC, around the same price as P&D:SMB Edition). Maybe, this time, it'll follow a much more traditional pattern for more casual aimed / Nintendo titles (quite lower pts than actual sales at debut).
