In the comments to Matthew's last post, reader "santarl" pointed out that the Looney Tunes comics are no longer listed on the DC Comics website. I had to poke around but eventually found them mentioned on this page. The last one listed is Issue 165 due out on August 6 (featuring a cover with a race between Speedy and the Road Runner).
However, poking around Google reveals some comic sites with information about Issues 166 and 167. Some sites are taking pre-orders, some say pre-orders have been cancelled. These two issues are nowhere to be found on the DC Kids website (which is usually right on top of this sort of thing). Is anybody out here connected with the comics industry and know the status of the LT comics? They haven't been the greatest lately, but it will still be sad to see them go.
Looney Tunes #166 - was originally announced for Sept. 3, 2008
Looney Tunes #167 - was originally announced for Oct. 1, 2008 - Witch Hazel celebrates Halloween in "A Witch for all Seasons" as Porky Pig signs up for a bad deal in "The Devil and Bugs Bunny."
