New Kodak E100G and E100GX

Has anyone used Kodak's new E100G or GX films yet? Not available from my local film depot yet. As a user of E100S in 35mm, and 4x5 I would like to hear other members opinions on the replacement. From Kodak's data sheets, it looks as if the major improvement is smaller grain.

Thanks in advance.

Haven't tried it yet, but Kodak is sending me some samples as we speak. I'll post my findings on this thread once I am done with my tests.
