If you don't already have a copy reserved of the new Dark Horse series by Gilbert and Mario Hernandez, "Citizen Rex," then make sure you make a special trip to your local well-stocked comic book store and pick up one of the limited number of copies they probably ordered. I recall having a lot of trouble getting copies of "Speak of the Devil," and this new series looks to be a good one.
There's an informative interview by Jeffrey Renaud with both Gilbert and Mario about their new series at: http://www.comicbookresources.com/?page=article&id=21418
(found back in June through: http://www.comicsreporter.com )
Check out here and click the "Citizen Rex" cover for a nice full screen version of the comics cover and the first three pages of the story.
According to Dark Horse's website "Citizen Rex" issue 2 will be on sale August 12, and issue 3 will be on sale September 9.
While your on the Dark Horse site look here for Gilbert's new color superhero series "Dreamstar" which is on pages 13-20 of the temporarily relocated "Dark Horse Presents" online series.
