P4U2 will presumably have 20 separate character trailers while PQ had 24. The last of the PQ character trailers came out 4 days before the game was released, with Theodore and Marie on June 1. There are 5 P4U2 character trailers left, so if the current pace continues, they will be over approximately on July 24, 35 days before the game's release.
PQ character trailers started 146 days before its release (January 10). P4U2 character trailers will have started 126 days before its release (August 28), so it's relatively close intervals.
Just random stuff (bored at work). I'm curious to see how the updates will progress if they run out before August, because PQ had a bunch of trailers teased on the website for a whole bunch of stuff and there are
still PQ trailers that aren't out, according to the character pages. I might have thought they'd restrict the character trailers to one per week to make it to release, but I guess they followed the PQ strategy. There are still two tabs left on the website, so maybe those will bring new trailers and maybe stuff like PSC gameplay previews, a couple of story focused PVs and the game's opening will be sufficient.
Won't lie, I was kind of surprised at the time and still am a bit that
was revealed almost 3 months before the game will launch. It worked as a precursor to some of the media like the character's related DLC, story episode and trailer, but it's not like those things couldn't have been left to early-mid July to give the promotion an extra boost.
