CricInfo has a short interview piece with Andy & Grant Flower, who ar currently in the West Indies playing for a World XI against the West Indies Allstars. As you'd expect, the article touches on whether the brothers would ever consider playing for Zimbabwe again, to which the answer is a "Yes, but...":

Andy: "I walked away because of the state of affairs and not much has changed. Since then it has gone further downhill. I don't believe things will change unless the government changes, so that's the stage we are at."

Grant: "A lot needs to be done to save the game of cricket in Zimbabwe. We would love to help, but we can't work under the present bosses. Zimbabwe has been forced to field a team of kids and we have all seen the results. It's not the players' fault but I don't see them doing very well in the World Cup out here."

The same line as taken by a lot of former players, then - not before there's a change at the top, and there's no sign of that happening anytime soon.
