According to The Wrestling Observer, when Big Show kicked out of Ryback's finisher and then knocked him out for the win in their match on Raw a couple weeks ago, this was said to be punishment for Ryback using Goldberg's spear and the jackhammer without permission from WWE officials.

A Big Heel Turn & Several PPV Bouts Scrapped by WWE
There is said to be panic within WWE at the moment where creative plans are concerned, as ideas have been changing very rapidly in the past couple months with long term plans in a state of flux, reports F4WOnline.com.

Original creative plans called for Big Show to have his match against Randy Orton at Survivor Series, and then for Show to have an even bigger match with Triple H at TLC. Of course those plans changed, and it's being added WWE's new idea was for Big Show to have a WWE Title rematch against Orton at TLC in a Tables Match. This is why Show put Orton through a table on Raw a couple weeks ago, to setup that match.

That plan of course was also changed at the last minute and WWE has settled on Orton vs Cena at the PPV.

Additionally, it's being said another idea involved Big E. Langston remaining heel and having a feud with John Cena for the World Title, but that idea was scrapped as well, and now we've seen a full Langston face turn.
