It is hard to say really.
For example, warriors used to have 3 sets of armor in PvP creation mode. Now they got 6 with faction comming. Both assassin and ritualist started with 6.
It would also be ridiculous if assassin and ritualist not getting any support from future chapter (since they are uniqe to chapter2).
It is also believed that assassin and ritualist primaries can start from tyria.
It is entirely possible for dev to not feel any need to fulfill this on the 15k part, but that would mean the assassin and ritualist will be lacking in sets of armors. If they do not care about PvE'er, then Anet can live up to "no distinctive advantage".
It is also possible that Anet would just make less 15k per chapter comparing to chapter 1, that way, people still can buy chapter 1 if they really like chapter 1 15k. (from the look of it, chapter 2 only got 3 sets of 15k for each class... cantha, luxon, kurzick; comparing to the chapter 1, 4 sets)
If they do decide to add new armor in previous chapter for each uniqe class, then by the time of chapter 7 uniqe class, they will have to design and make 24 sets of armor for that class. That can be outrageous. Then again, they can always hire new recruit.
.......I don't think I needed to type all that. oh well.
