Another thing that could be possible. Since there may end up being nearly 220 episodes to produce for this season, there may be budget cuts. Season 28 was cut short, and those 11 outstanding episodes were added to the Season 29 contract. As a result of the greater number of episodes, they had to stretch the season's budget by offering fewer luxury cars (plus there were only three playings of 3 Strikes that season, that season's first playing in February 2001), plus Janice and Kathleen were both terminated - again, likely due to budget cuts.
Despite that there may be fewer luxury cars offered in the upcoming season, I suspect that a majorly expensive car could be offered on the first new episode of this upcoming season, and none of the big three car games will be played for it - with a setup designed to easily win the car, possibly to allow the show to come back with a bang.
Also, considering the taping dates for these upcoming new episodes, could this imply that these may actually be the final weeks of Season 48, and maybe this show may be cancelled in favor of a talk show? I read something about a talk show hosted by Drew Barrymore coming to CBS daytime (and it was reported it was finalized for the upcoming seasoni), and we know that the two soaps on CBS are renewed, so that leaves The Talk or one of the two remaining game shows, as candidates to be replaced by a talk show.
