"Securities Covered by Price Test Restriction: The rule generally applies to all equity securities that are listed on a national securities exchange, whether traded on an exchange or in the over-the-counter market."
Yes OTC is included. 60 days for SEC rule to go into effect, 6 months for brokerages to enact the rules. You can expect it to be toward the end of those 6 months. They have to finish all their short positions after all :)
