Will a major league baseball player ever hit five consecutive home runs?

I know that Mike Schmidt, Willie Mays and Mark Whitten, among others, I'm sure, have all done it in the same game. Also, Art Shamsky once did it over the course of two different games, and Nate Colbert once hit five in a doubleheader, but not consecutively. Do you think anyone will ever hit five in a row? I have to wonder. That's a feat that you don't hear mentioned all that often...
