At this point, it's uncertain, as the Times Union reports:

Senate Republicans continued to refuse to say whether they will bring a bill legalizing same-sex marriages to a floor vote, drawing charges they are delaying action for political reasons.

... On top of personal misgivings -- many of which are rooted in religion -- Sen. John DeFrancisco of Syracuse said he was urging cohesion among Republican members because a vote might hurt their razor-thin 32-30 majority. He said Bloomberg's optimism was "maybe wishful thinking."

... Opponents and supporters remained at the Capitol, but the Rev. Jason McGuire, a traditional marriage lobbyist, interpreted the delay positively.

"I think it's a good sign. I think they're seriously considering the short-term political implications but also the long-term societal implications of same-sex marriage in the state of New York," he said.
