Doubt that we will have something like that, all renamers work on it in their freetime and we don't want to force renamers to update something until a specific date.
We already have alot new & updated DATs but I also think doing another release yet isn't needed, there are still some DATs that get checked currently and it would be nice if we have them completely checked before another release.
For example, I would really like to get done with Atari 8bit Applications and then have a release and I guess that mai would also like to finish checking the Amiga DAT first.
