The U.S. Supreme Court has put Sarvis v Alcorn, 16-781, on its February 17 conference. This is the case over whether Virginia can constitutionally always put the Democratic and Republican nominees at the top of the ballot. The Court won’t release any information about whether it will take this case until February 21 at the earliest.
So far the state has waived its right to file a response. If the Court is interested in this case, it will probably ask the state to respond before February 17.
