Oh, shush, please! Some devs may see it and decide that "okay, since modders are going to do it for us anyway, we can ditch the whole college thing and use our spare development time to cut a few more features and add more dragons" ^^
They're already in crunch time; no new features are being added anymore, it's all bug removal and play-testing now. If it's not in already, it's never going to be.
EDIT:
I'm wondering what the 12-20 perks for Speechcraft will look like, and whether any might be helpful for this sort of quest.
I think a few might increase how much NPCs like you, and a few will probably replace Mercantile's functionality. It wouldn't matter if they didn't affect dialogue options, as even in Oblivion's vanilla scripting you could check against an ability score.
A bit off topic, but I wonder if Speechcraft will include ways of encouraging your companions in order to make them more effective. I realize that companions are optional, of course, but if you're going to choose to work with people than it makes sense to take and use Speechcraft as a skill in order to communicate/interact with them better, and possibly improve their morale and efficiency. A bit like a traditional D&D bard, actually.
