It’s been quite a long time since there has been any major news on this group. Mainly this is because of the destruction of the BLC near the ending of one of DC’s many reboots starting from 2013 ~ now. With Saint Walker as the last (canon) remaining Blue Lantern and his role being relegated to that of “cameo apperance support for the Green Lanterns,” it was hard for fans — old and new — to get stoked about stories when it appears that DC had killed them all off without any strong conviction to bring them back.
That appears to be on the change.
Without spoiling anything, I believe there is a very good chance that by the end of 2017, the storyline will have found a way to return the Blue Lanterns from thier purgatory. This is not based on insider information, this is based on reading all of the Green Lantern storylines and the intersecting sub-stories developing over the last 6 months.
For those interested, the Saint Walker storyline begins in Green Lantern #14, which can be found here on the DC website (or at your local comic book shop!)
I’ll keep this page updated as the issues keep coming out. I’m extremely hopeful for this new event, and I hope it brings all of our alien Brothers, Sisters, and Persons home!
