One of the most titanic shifts that happened in the pages of Green Lantern, following the decade when the entire Lantern Corp was wiped out, was the invention of several OTHER Lantern Corp. It was the invention of Geoff Johns, and expanded the Green Lanterns so that they were a part of a larger rich mythology. Suddenly there were tons of rings zipping all over the cosmos, and virtually every character of note in DC's continuity has, at one time or another, worn at LEAST one ring. It seems to be a fairly popular concept, but it effectively removes everything narratively unique about the Green Lantern Corp. The primary function of any story element should be to enhance the central story, and the introduction of so many other Corps simply doesn't do that. Rather than building a mythology, it supplants it for another one.
So we're completely removing almost the entire notion of alternate Lantern Corps... but we ARE keeping a couple of the characters introduced in that arc. Saint Walker, for example, is a very fun addition to the world of the Lantern Corp, especially as he's depicted in the Green Lantern Animated Series (represented here by some very nice fanart by Deviant Artist dou-hong). While an entire organization of ring-weilders who are empowered by hope and who enhance the powers of a Green Lantern is unweildy and doesn't work within the larger tapestry of the Lanterns, a single ring-weilder with a unique skill is wildly functional.
One of the only other characters from the multi-colored Green Lantern Corps that we're using is Atrocitus, again because of his appearance in the Animated Series. Both Atrocitus and Saint Walker have their stories built on the idea of a Forbodden Sector: an area of space that the Green Lanterns are forbidden to opperate thanks to the rise of the ancient Manhunters many years ago. This territory functions as a sort of frontier where Atrocitus can raise his armies, and where Saint Walker can operate as a lone hero, traveling the spaceways to deliver hope to the people and right wrongs, like Kane in Kung-Fu. By removing the bulk of the multi-color Lantern mythology we've stripped it of a lot of dead weight and instead create a cool, singular story featuring a unique alien hero. It might be wildly different from the way these characters were DESIGNED to operate, but it brings a far more focused and more entertaining narrative, which ultimately is the whole point.
