With the new addition of the VPK Add-on feature to L4D, we can expect a release around that time.
Honestly, making all of this stuff is a bitch to work with, let alone getting everything to work without a hitch. So I have decided to wait until the Add-on update is released before I will release a final version. The beta will probably come out before then, just to keep you guys happy, and to work out some preliminary bugs.
AS you may or may not know the beta tools are going to be released next week, I will most likely try to throw together a beta once I figure everything out. ETA 2-3weeks after release
