Isn't money the reason why he gave up pool in the first place? Now that the IPT is finally here, there is significant prize money to be won. Just look at the total first place prize money for the next 2006 season...1.25 million dollars!!...and that is the prize money ONLY for first place! Isn't that enough motivation to get your skills back on track?
And personally, even if money isn't the issue, I think Mike has too much pride and ego to finish his career the way he did against Efren. Deep down, Mike still thinks he's the best pool player of all time and he wants the world to know it. He wants a second chance to prove himself. And BTW, he's only a few years older than Efren, and I believe he's still younger than Parica. You'll definitely see him again, and I won't be surprised if he makes a significant impact on the 2006 season. Cuz now, he has motivation.
