Yes, it's quite common for the Public to extend their popular productions. How long, though, is tough to say. Some extend for 1 week, others extend for months. Assuming the show isn't totally panned, there will likely be reasonably high demand for it. So I would guess they'll extend for at least a few weeks to a month. Maybe more, but we also don't know yet what's scheduled to go into the Newman after The Visitor. They'll probably have a winter/spring show in that theatre, so it can't extend that long.
