FWIW, the show has gotten back into the flow, becoming a throwback to its glory years of the late 80s-early 90s, when Bob and Rod were running things. I love how they modernized a few elements from that long-gone era, like the SCSD split-screen arrow and the announcer's (George) calldown window. Safe to say, Drew and George are this era's Bob and Rod (with Rich being Johnny), and it's great to see them have fun during the course of the show, even if they sometimes go over the top.
If they do revive the half hour Nighttime price is right, they should either air it on CBS or ABC Sunday nights during the summer time with the same models and announcer from the daytime show. The host could be from The price is right live.
While in theory this could work, I don't see it happening, because this isn't 1985 anymore. And ABC already has a lot on their plate with Celebrity Family Feud, Match Game, The $100,000 Pyramid, etc. Even CBS has a strong primetime lineup, and I don't see them messing it up just to squeeze in a few nighttime airings of TPIR, half-hour or full.
