A little more speculation...buyout by TGC would be a win/win/win:
Advantage for WGT (Chad): $$$ and retirement
Advantages for TGC: $$$ in the form of advertising and possibly subscriptions, prestige of owning the #1 online golf simulation, avenue for promotional links with PGA and other golf associations, expansion of media presence.
Advantages for us, the customers: product taken out of beta, new courses added most certainly, probably many new brands of golf equipment added, quite possibly lower cost of premium equipment due to increased volume of customers (given that TGC's marketing department is savvy enough to see the advantage) and possibly a different game platform (no more Flash).
Maybe I'm crazy, or just maybe I'm crazy like a fox...time will tell.
