Actually let me caveat that a bit - not everybody who was new to the team went to Arizona so obviously some of the new players had their photos taken in Okinawa. But I'm pretty sure that the cards of the Fighters top two draft picks (Kenta Uehara and Takayuki Katoh) and their two new foreign players (Anthony Bass and Chris Martin) feature photos taken in Arizona:
Another thing that I mentioned in the post is that the theme of the team cards was training camp. There's absolutely no question about where the photo on the Fighters' team card was taken:
I'm kind of hoping that there will be a subset in the Fighter's team set devoted to their trip to Arizona but that's probably unlikely.
