Yes Torchwood is an anagram of Doctor Who, it is also the project name for Doctor Who when the new series was in production so that no one would guess what show was filming. Now that we know about Doctor Who return, they had no use for the name so they gave it to their spin off series.

The new season is about to start, and we expect the return of the Rani and Davros. At least so says the rumors.
