How many validators are we expecting?

As the title states, I'm curious what the estimated number of validators will be when PoS goes live.

I've seen a lot of talk about what the rewards will be for staking, but I can't seem to find any mention of what the estimated number of validators could be.

As far as I understand, it's required to run a node in order to be a validator (please correct me if I'm wrong). So would it be safe to assume that the number of validators at launch will be similar to the number of nodes currently running on mainnet?
