This situation with BTC-e is not important just to BTC-e but for the whole crypto exchange system.
For example, SimpleFX (exchange?) is not allowing transfers between crypto and hard currency balances. You can trade crypto-hard pairs but you can't: deposit crypto then buy usd and then use that usd to fund mt4 account or to withdraw that usd bought onto EXCHANGE(?). FXOpen does not allow US citizens. Will the rest of exchanges follow those rules?
