Only two previews remaining, and today’s team is National Taiwan University +1 ironwood branch. This team already participated in World Finals in 2011 and had not won medal with 6 problems solved, but they make good use of this 2 years with outstanding progress in both personal and team competitions.
In 2010 team finished 3rd in Kaohsiung and 1st in Jakarta Regional Contests. In 2011 they placed 1st in Kuala Lumpur and 2nd in Hsinchu Regional Contests, but another team from the same university was selected. In 2012 they won both Kaohsiung and Jakarta Regional Contests. After Jakarta regional they were interviewed, you can view it here.
Pretty impressive results in regionals (they had beaten University of Tokyo team in Jakarta) and recent personal result (peter50216 is second in Codeforces rating, kelvin and peter50216 qualified to upcoming TCO onsite) make them quite dangerous. I will give them 60% chance for Gold.
