Chris Marshall at the Collected Comics Library reports that Absolute Green Lantern: Rebirth, due April 2010, could include not only Green Lantern: Rebirth, but also Green Lantern #1-6, collected in Green Lantern: No Fear.
[Note: Rumors fly fast and furious especially around convention season, and indeed we're now hearing that Green Lantern: No Fear may not appear in Green Lantern: Rebirth. In all cases, advance solicitation information should not be considered final until officially solicited by the comics publisher (see, for instance, the change in the Final Crisis collection's contents). The below post has been edited to reflect the new status of the Rebirth information, and we regret any confusion this caused.]
As pleased as I am to see Absolute Green Lantern: Rebirth (because, hey, why not?), the possibility of including No Fear would make for, in my opinion, a terrifically uneven reading experience. Green Lantern: Rebirth is quite self-contained, whereas Green Lantern #6 ends on something of an inconclusive note, and the art there by Simone Bianchi differs drastically from what came before.
Granted, those last issues include an appearance by Black Hand, he of Blackest Night, so no doubt that would be a benefit.
But putting No Fear in Absolute Green Lantern: Rebirth would beg the question, as one fan asked at the Geoff Johns Spotlight panel, is there more on the way? The subsequent issues of Green Lantern are good but aren't necessarily notable, but there's long been speculation about an Absolute version of The Sinestro Corps War; stretching out Absolute Green Lantern: Rebirth would seem the first step toward a sequel.
