As fun as it is to watch beta testers speculate like they know what is going on, I think it might be time to bring some truth into this thread.
First of all: It is true, there are no plans at all to include the pacific maps in the launcher. Why?
When a map is released through the launcher, we take responsibility for it, for maintaining it, fixing bugs and making sure it is of good quality. As you may have noticed, we don't even have enough manpower to do this properly for all the official maps.
That being said, we are happy to include any custom map that has a high quality and does not require us to do much work on it. The thing with these pacific maps (at least the ones I have seen) is that while they are better than most custom maps, they are also done in a completely different style from modern FH2 maps. These are BF1942 maps and it shows. They are extremely scaled and unrealistic in their style. Imagine somebody would have made a 1:1 remake of BF1942 Omaha Beach before ours was released. Would you have liked that in the official game? And the pacific maps are all on that level, basically, with the fantasy bunkers and the scaled terrain etc.
Secondly, where do these assets come from? I don't know all the goings on, but afaik many of them were bought from modeling stores. This is fine of course, but FH2 has never included ready made 3d assets like that and is not about to start. There is a certain reputation to lose here.
Thirdly, there is the question of historical accuracy. You may laugh that off, but I am not talking about minor things here, but ships that are completely out of place or Japanese troops running around with smgs that would only warrant pickup kit status by FH2 standards. Again, this is not a question of quality, but of fitting in with the rest of the content and maintenance.
On top of that, including these maps and releasing them through the launcher is not as easy as you might imagine and would probably set back Eastern Front development by at least a month, and that is conservative.
So in conclusion: These will stay as map packs.
