1) Yes, I think Eastgate had what it takes to have a long poker career and be a winning player, because he played alot before he even won the Main Event. Then he followed it up a year later with a deep run finishing 78th. Only Dennis Phillips, Greg Raymer, and Dan Harrington have had similar type runs since the boom in '03.
2) I enjoy poker too much to quit. I'd invest wisely and use the interest generated to sustain a pro bankroll.
3) Gus will be fine. We know he's at least a huge tennis fan, perhaps he decided to be in South Africa
for the World Cup
