Full video of Putin's speech from here:

He doesn't explicitly saying that TschVK Wagner is rebelling. Maybe he means those who attacked Wagner...
And ofc, if Wagner is the one that has to be put down, that's a considerable experienced fighting force Russia still needs, and put into use after the leaders' heda are chopped off.
Or perhaps he expressed himself vaguely on purpose. There could be competing groups (Prigo vs. Shoigu) and he waits and sees who is winning first. Then the loser will become the real culprit of the mutiny.
Is there a video somewhere Prigozhin replying?
