1) in name meanings- arthur- possibly a relation to king arthur? who was a great leader (and mythical, too, right? but then, he could have been a wizard or something

2) cornelius fudge will probably get the boot, now that people know what a doofus he was. and since mr. weasley already works there, he could get a (very) big promotion! (i'm a bit skeptical about this, since there are so many wizards working at the MOM who are much higher up then mr. weasley.
also, in the topic "unification" nothlit states that at the end of the series, there could be a unification with muggles and magical people... who better to bring this about then mr weasley, as a muggle-loving minister of magic?
have you heard any more evidence of this? what do you think?
