I believe it is a draw.  In order for White to win, he needs to capture somehow
Black's Bishop.  Because the Bishops are opposite colours, it's impossible to
trade off to a K+R vs K+N ending.  Rook vs. Knight is a win for the side with
the Rook in most positions, with a few positions which the side with the Knight
can draw.  Rook vs. Bishop is a theoretical draw, unless the side with the
Bishop falls into some theoretical positions which the Rook is able to squeeze
the win, and with the use of tablebases, it's most likely that the side with the
Bishop will draw.
