There is about ~340M Steem in the supply

If these exchanges that powered up don't support the drop

binance-hot 30M
huobi-withdrawal 7M

The Hive supply would be about 240M - does that sound right?

I am guessing that the exchanges will try to support considering that they might open themselves to legal action for not due to the locking of customer coins. But, they might not care or have time to enact the changes they need.

Regardless, this would mean that the Hive supply would be almost identical to the initial mine supply with the difference that it is spread among tens of thousands (real users) of accounts + alts.

Do you think that this would make a significant difference 4 years from now?
