I can answer that quite simply:
 * Q: Are there going to be more/different endings or ending DLCs in the future?
 * A: No.
 * Q: What is BioWare adding to the ending with the Extended Cut DLC?
 * A: BioWare will expanding on the ending to Mass Effect 3 by creating additional cinematics and epilogue scenes to the existing ending sequences. The goal of these new scenes is to provide additional clarity and closure to Mass Effect 3. Source

The main criticism is not the plot holes, it's the ending itself, and the fact remains, the ending is not being “fixed” or changed; it’s being extended.
