From FFWD’s April 15th paper, last year:

Whether other political parties will court Taylor remains to be seen. He has ruled out crossing the floor to another party before an election is called. “If I were to make a decision… then I would wait until the next election or resign and go through a byelection,” he says. “I might sink back into obscurity because, frankly, that’s where I was going and where the rest of the caucus is going with the Liberals.”

You can also find Taylor’s signature on a contract promising to do what he describes above, here.
