Something I've noticed is that we seem to have a situation of "a watched pot never boils." All the DLC so far has been a blindside, either for all of us or for some of us. Obviously, not everyone is a
complete blindside, like Steve and Byleth, but all the expected characters had something that made others hesitant of them. Maybe they were too old, or too recent, or were just overshadowed by someone else.
That being said, it's rather illogical to just say "hot topic character=Auto-deconfirm." In addition, I realized that a major hot topic has gotten in with Steve; They just weren't a hot topic when they actually came. Perhaps characters like Crash and Dante will begin to drop over time, only to actually get in while their support is on a low.
Basically, I'm telling you to stop expecting Dante and Crash so the Spirits of Screw You up above let them past and we can get our hands on them sooner. Perfect logic, guys!
