I meant purely Persona based, should have clarified that :S
Ah. Most people here did not think that much of anything Persona was going to be shown off in the upcoming Famitsu, given the poll, so at least the majority here are probably content with the Margaret news.
Kokonoe was announced in September, BBCP launched in October, and she wasn't available until November.
Edit: Technically the same is true for Terumi, but you got him release day if you had the voucher.
The situation isn't comparable when there are many more new P4AU characters than there were introduced in BBCP, and when there have been two post-release DLC characters announced as of now (Marie isn't like Terumi at all because she will not be playable at all on day 1, meanwhile I could play Terumi just fine when I imported BBCP). This is combined with the fact that the game obviously follows a weekly cycle of regular news, which BBCP did not.
