Whether or not Tiger Woods wins another major will only be answered in the future and any current opinions stand a 50/50 chance of being correct.
However, what is 100% certain is that every time Tiger is playing golf, winning is a possibility. Winning and winning and winning is a "sweet spot" in time. The words of an old friend, Topper Hagerman. Tiger had discovered that spot for a number of years. During that time it was all about playing golf. Now Tiger's life has changed.
As Greg Norman said during a recent interview, published by golf.com on 9/28/11, "Tiger, when he dominated, had a single-shot approach. It was only about the golf." "Now there are so many distractions..." A key factor in a champion's ability to win and win and win is having the skill to focus and the ability to do away with all distractions. In the case of Tiger, there are now many new distractions which he must reduce or eliminate.
These new distractions are more powerful than the superficial comments and criticisms and sponsorship questions, as they come from within. Tiger has been forced to question himself to the very core of his humanity. His entire personal operating system must now be reprogramed. He had the recipe for winning at will, but that piece of paper is now lost. It now must be recreated and this will take time.
The good news is that Tiger has the ability to focus - perhaps better than any athlete in the world. Finding the internal balance will be the key to Tiger Woods returning to the top of the golfing world. If he can find this balance, we will see the return of a champion.
