1. "Wheel" and "J!" are still at or near the top in syndicated program household ratings and will remain there for years to come. (Preferred demos is another story, but the household numbers will still carry them.)
2. The two shows are, barring any surprises, remaining in production until the end of this decade, at least.
3. KenJen was an aberration. A very profitable aberration, ratings-wise, but still an aberration. "J!" will still do well enough without him.
4. Friedman could be considering bringing back returning champs, but I can't really see them taking off the limits, not when the show in the course of its history actually *reduced* the number of appearances a champion could make (five to three in the late 70s). Despite that period in the late 80s-early 90s, "Wheel"'s run long enough without traditional returning champs that I don't think bringing them back would make any big ratings difference one way or the other.
