The thing is (to oblige Doublemochaman), Gmail was stuck at the Beta stage for something like 5+ years, but that didn't prevent dozens of millions of users from around the world from happily using Gmail as their primary webmail provider. Even at the Beta stage, Gmail beat everyone else's webmail solutions in their non-Beta stages. And when Gmail finally emerged out of the Beta stage, it was clearly the best webmail provider this world has ever known.
So, if it takes 5 years for WGT to get everything right and become the best golf game ever, why not? The game is perfectly playable and enjoyable even now, as it is. (I seem to be among the lucky site users unplagued by software issues.) Of course, I really am waiting for variable pin locations and new stroke-play courses, like everyone else.
