Leading up to this 2012 softcover printing of THE DARK PHOENIX SAGA, every bit of info I'd seen, including this Amazon page, had stated that it would include the oft-reprinted main storyline from Uncanny X-Men # 129-137, plus related material from Uncanny X-Men #138, Classic X-Men #43, Bizarre Adventures #27, Phoenix: The Untold Story, and What If? #27. Basically, it was advertised as a softcover edition of the 352-page, 30th Anniversary hardcover from 2010, while retaining the price of the prior softcover edition from 2006. I was amazed that Marvel would include so much additional material for such a reasonable price; however, as The Dark Phoenix Saga is perhaps Marvel's most popular storyline, I figured that they'd realized how this particular book would never be a loss for them (they could give away an entire print run and still continue to make money off of it).
Just before it was to be released, I heard from various sources that the solicitation info was incorrect, and sure enough, it turns out that this edition only includes the standard Uncanny X-Men #129-137. Of course, the main story is still a great read over 30 years later, and the art is incomparable; however, what was advertised is not what was released. As of the date of my review, Amazon and most other websites still contain the wrong information for this book, so be sure you know what you're getting.
