Hints and clues: SPOILERS
This issue came out in December of last year, so I guess now it's ok to point out some of the little things happening in this book.
CONTAINS some SPOILER ACTION.... from this issue and more.
One of the best things to this amazing climax is the one on one battle between Hal & Sinestro, it's some of the most satisfying reading I've done in years. The next thing coming up is Blackest Night, however, it's next year. If you notice on one of the last pages, after Anti-Monitor becomes the black battery, a symbol on the ground, the symbol is the same as Black Hand's symbol. His quest for a lantern ring was a minor part of Rebirth. This leads many to believe that Black Hand will lead the Black Lanterns. Since there are black lanterns, what about a white lantern? Let the rumor mill begin. In the current G.L.C. comic, Mongul is on a ring collecting spree, with numerous Yellow Lantern rings under his belt. Many think that he may collect one color from each spectrum. Collecting all of the rings, all the colors of the rainbow together equals a white lantern. However, Mongul becoming the only white lantern isn't the best thing for the DCU. Many speculate that Kyle will also become a light lantern. The hints are there, reread Green Lantern from Rebirth to now, the hints are there.
