There is nothing wrong with pleasing fans once in awhile, because if the fans aren't happy then they are less likely to buy the books.

Also, I don't consider HoO completely independent from PJO, as the first two books make a lot of references to the original series and the world this takes place in is much easier to understand if you read the series, as in HoO they kind of just skim over it. However, th HoO series has a story all it's own and needs to stand on it's own feet instead of relying on the PJO series. Meaning that some of the older characters may be pushed aside in order to make room for new ones. I mean while we may not have seen that much of Camp Half-Blood this series, we have been introduced to a ton of new Roman characters that fill in much the same role as the minor characters in the PJO series.
