Clipped from Wizard Magazine:
Howard Porter, 2007, says, "Jonny Quest is still happening. It's just getting done very slowly! I have through the second issue drawn and most of it colored. If there is ever any down time I'll be working to complete it. Much like Shazam, Jonny Quest is a fond childhood-Saturday-morning memory, so I look forward to finishing this up. And I didn't know that Joe is working on Supergirl. That will be great! Way to go Joe!"
Dork Note: Well, it's now 2011 so my guess is this NOT happening.
