This is all about reading between the lines. It is not based on an actual source, unlike other recent DC articles.
But we're looking at a couple of Amazon listings. One for Team 7 Vol. 1: Fight Fire With Fire and one for Sword And Sorcery Vol. 1: Amethyst.
Both seem to contain seven or possibly eight issues worth of content which is high for a New 52 trade paperback. They usually contain five or six. Almost as if they were the complete run of the comic. As it was for, say, G.I. Combat Vol. 1: The War That Time Forgot.
That would suggest, purely on the Amazon listings, that Team 7 and Sword And Sorcery may be cancelled already and that we are looking at a new Wave of titles in May or possibly June.
