I am developing 2 VNs. I am not focusing more on one than the other. I work on each update as best I can with the time I have outside of working a busy full-time job and taking care of family. Sometimes it takes me longer to update one than the other but not because I just 'spend more time' on one than the other. Once I complete an update to one, I begin work on the other. So yes, it can take a while between updates.
