I think by the lack of responses from anyone affiliated with WGT, you get your answer right there.
They intend to do nothing about sandbagging, cheating, dual accounting etc etc. As far as I can see, this is a great game (much better than anything out there IMO), although the spirit and fairness of competition is not something that WGT takes stock in.
We will continue to get upgraded features that cost money and enhance the "playability" of the game,which is what everyone wants...but I'd forget about anyone at WGT being proactive about cheating and fairness...If getting a new course takes 8-12 months, imagine where "finding sandbaggers" falls on their list.
