As with many things, there are ways around rules and regulations. In case CFTC does reduce leverage, there's no reason a broker can't introduce a leveraged derivative, like equity ETFs. SSO/SDS and QLD/QID are only 2:1, but a new derivative could just as easily be 100:1 or higher. And liquidity would be less of an issue since most Forex brokers are also market makers.
