I really don't see anything that's a sign to the 'end of IC2' or the 'end of Minecraft Modding'..
I will say, however, we may encounter a race situation on copyrighted content and the defense of said content soon. Since we have so many mods doing the same thing, this is going to be a highly debated issue (one that may, in fact, implode the community), as far as saying "who should have credit for what" and "what content is considered 'original'?"
As far as that goes, I do believe we need to distance ourselves from Modpacks in general, as the resulting Copyright claims will create a new form of legal confusion. Plus, given the fact that neither Alblaka nor Eloraam are around to protect their individual works, making copyright claims on their behalf will be that much harder. I would guess, however, that such distance be used in order to preserve the integrity of this mod, so that violations of this matter don't get haphazardly raised by the uninformed and naive...
This is a good sign as far as getting a more official class of support for Minecraft modding in general, but it's going to hurt, legally, alot of people in the meantime. We'll just have to wait and see how this truly plays out...
