Will all four #1 seeds make it to the Final Four? Who will win?

Tweet

For those of you outside the U.S. who don't follow, the Final Four is the culmination of the college basketball tournament which some refer to as March Madness. There are 64 teams in four regions and each region has teams with seeds from #1 to #16. In the history of the tournament there has never been a Final Four matchup with all four #1 seeds making it to the last four teams. This year, there is a chance of that happening. Two #1 seeds already won yesterday (UCLA and North Carolina) and Memphis is well on there way to winning as I write this. So if you follow (or even if you don't), do you think this will happen? Whether or not it happens, it will be decided in a few hours from now so the discussion here may be limited. That's why I'm asking the follow-up question, who will win? I am hoping the UCLA Bruins will it all and get another national title. Of course, I am somewhat biased because I graduated from there in 1995 - the last time we won a national championship. What do you think?
