Starting Oct 11th, Quints by Surprise (The Joneses) to be replaced by Texas Quints (The Wilkinson's)? Not exactly sure if Quints by Surprise are airing on a different time or date. Nevertheless, it does look like TLC is moving on.
Kate Plus 8 'may' appear in more "specials" (winter, spring or summer break?) but for now its gone. Twist of Kate is now scheduled for a December release. Still not sure if Quints by Surprise or Texas Quints will be as 'popular' as the Original J&K Series.
As for Texas Quints and Quints by Surprise, both shows seems to be a "series specials", just like Kate Plus 8.
Texas Quints: Birthday Madness - TV-PG
The Wilkinson's plan a party to celebrate the Quints' third birthday but bad weather could put a damper on everything. The Quints go wild when Jayson tries babysitting solo. Rachelle fears her cake and Jayson's petting zoo could both be major disasters.

From what I can see, one of the girls (doing the Old Spice Parody) is a pretty good actress. She did mumble through a few lines, but it was a pretty good parody.
