Did I just miss any mention of this or did noone report it?
This was mentioned in Hachima, and this part is on PS Blog (OreShika2's Production Log 31: Summer 7/17 Release Date).
待ち望んでいたファンの皆さんに加え、新しい層がどれだけ手に取ってくれるか?
『俺屍2』の結果が、SCEJAのRPGについての結論になるかもしれません。
そう思うと…7月17日に向けて、より一層気合いが入ります!
How many new players will pick this up, in addition to the fans who have eagerly waited for it?
OreShika2's result might become [the basis for] SCEJA's conclusion about RPGs.
With that in mind... [We] work harder towards 7/17!
You want new Wild Arms?
Buy OreShika2.
EDIT: The Wild Arms comment isn't from SCE. It's ATXAlchemy's opinion.
