These are all part of "the game". I remember this same exact thing happened after season two. Weiner wanted a certain amount, AMC pretended like they would go on with or without him to call his bluff. But then the lawyers eventually work something out. In the meantime fans are left wondering if their favorite show is going down the tubes. Its disheartening, but usually these things are worked out. In the case I mentioned earlier, AMC caved and paid Weiner what he wanted, but also locked him down for the third AND fourth seasons. So these negotiations aren't always bad. Weiner will return, I'd put a decent amount of money on it.
