He might just be baiting, but generally it seems when super hero movies/shows try to fit in more villains at once, they tend to be less interesting because neither plot point gets the attention it deserves. Look at both Spiderman 3 and Amazing Spiderman 2. Both went for multiple villains, both sucked.
Of course Daredevil is a series, not a movie, but I dunno if itll really be able to do justice to both plotlines while having them run against each other.
Either that or Punisher will get dealt with before the final events begin and punisher fans will be dissapointed they were just the opening act.
