I'm all for an Indy ongoing monthly. Been waiting 12 years for new Indy comics!!!
The last I heard over at the Dark Horse boards is that they are waiting to see how well the new comics sell ("Tomb of The Gods" mini and the 2 issue Adaptation that's out today). Rob Williams (writer of Tomb of the Gods)already has story plans beyond the first new mini series but Dark Horse is waiting to see how the first one sells.
I started an Indy thread over in the Star Wars section where the editors/writiers drop by and give us some status on any upcoming books:
Feel free to start up ALOT of Indiana Jones threads over there too! New Indy fans are especially welcome!
Drop in a line and say hi in the Star Wars section and talk up the Indy comics! (it's the main spot for the Indy talk until they set up a new board section for Indy fans)
Alot of the marketing Dark Horse people should see the demand on there too.
The more demand.....the more Indy comes out!!! (and buying up all the new comics out now would help!)
