They are still hiring out of the CTI schools (collegiate training initiative...google it). They do off the street hiring but it is mainly for places people don't go (Seattle, Albuquerque, and NY).

From the stats I have seen something like 1500 people took the AT-SAT (the test everyone takes to become an ATC) for one of the off the street hiring campaigns the FAA did. Of those 1500, 80 passed, and a <10 were hired. So you're best bet is to go military or to a community college near you if you'd like to pursue ATC.
