I'm going to be joining in on the BULLY2SA project as well soon.
That's on hold from my end as well, that damned track is driving me mental.
But yeah, this reminds me of GTA modding, when everything has been found it dies down a bit, but then an expert modder finds some way of inserting new things (Add-on scripts, new models, sound replacement etc,) and then it's rezurrected.
We just gotta wait for someone to make a new tool for Bully.
