I'm amazed at how many people would actually shell out more cash for a DLC of a proper ending.
If EA would pull THAT stunt, basically ripping customers of just so they can finish the game properly, that would propably be a rather valid excuse for DLC piracy. Good lord! Spent 70€ over retail CE FFS.
I would be VERY glad if they would extend the ending, a proper closure and no WTF feelings but if they would dare to ask money from it I personally would get a nerd hissyfit-rage of epic proportions.
