Miller, 33, is in the final year of his contract and is scheduled to become an unrestricted free agent July 1.
Contract talks between the Sabres and Miller's camp haven't progressed lately, though the two sides are expected to connect either during or after the Winter Olympics, a source close to the situation told TFP.
For the time being, Miller is still "waiting to see what the (team's) plan is."
"We haven't talked anything with regards to contracts and we haven't talked about anything in regards to trades," Miller said. "They're doing their business."
The goaltending market is fairly thin and Miller has a say in terms of where he'll end up, if dealt.
The Sabres would like to keep him, but all signs point to Miller testing the free agent market this summer, furthering speculation that he'll be dealt before the March 5 trade deadline.
"I have a limited no-trade agreement and that's something I put out there in the summer," Miller said, "it's not something they approached me (recently) about altering or changing or discussing."
