That's pretty much all I got, folks. According to a post on the blog for Harkham's L.A. book and music store Family, Crickets #3 is "happening soon." That appears to be the cover up above.
Around this time last year, Harkham announced the cancellation of the series, then published by Drawn & Quarterly, due to Diamond's new minimum-order thresholds. At the time, the Kramers Ergot editor and cartoonist said the third issue "will come out in some DYI form in the next couple months." I think I speak for all of us when I say better late than never!
