Question about villagers coming and going

[MamaMyers]

I had 10 villagers, 2 just left leaving me with 8, now 2 days later and I still have yet to get anyone new...how long does it usually take? or do I have to have less villagers to automatically get a new one, with out getting one from friends?

I think it can take up to around a week but is usually quicker, the longer you go without someone moving in the more likely someone will arrive the next day.
