I mentioned in the Supermarket Sweep thread it airs at 8:30P and 11:30P starting January 15th with episode #1131.
Also starting that week, they're adding more black and white shows to the lineup, but only on Tuesday and Thursday (repeating on the weekend.) The B&W blocks on those days will now be Password, The Name's The Same and Beat the Clock. Password starts with the first B&W nighttime show, The Name's the Same with the 8/6/52 episode, and Beat the Clock with what's listed as the fourth show of 1952. They're all in 40 minute slots, which I guess means they'll include original commercials like the other B&W shows do.
