Yahoo owners will be the richest in the world by 2015....true???

If you mean just the owners, it would depend on how their portfolios and other business dealings are working. I don't think just Yahoo will get them there. The guys at G are too far ahead for that. But the Yahoo guys could possibly get involved in something that could put them in contention on an individual basis, rather than a company share.

Yahoo owners have a lot of moola and probably will have even more by the year 2015, but I don't think they will be the richest in the world. They will always be second to Google, if even.

It could be true because they are the next big contentenders who are fighting it out with the giant named google. If they could keep on this competition till that date, you never know they will be the richest at that time and google could be fighting it out for that spot with yahoo at that time.
