What I have read Haynessville is the exception to most current gas plays.
The dry gas is the reason their drilling fell so sharply with the nat gas prics while drilling in the Marcellus and Eagle Ford (gas areas) continued to climb.
Fayetteville Shale is similar and heard that Marcellus has areas that are dry. We bought a 200 million per day system down in Leon County that is also dry from Encana, but you are right most of the other plays are wet thus all the drilling.
