The crisis-hit European Union, Belarusian or Russian human rights activists, or a non-violent protest theorist whose ideas inspired the Arab Spring? Speculation ahead of Friday's Nobel Peace Prize announcement is rife.
The Norwegian Nobel Committee that awards the prize had 231 individuals and organisations on its top-secret list, with the laureate to be revealed in Oslo at 11am (0900 GMT).
The field of possible winners has long appeared wide open, but by late Thursday, observers were circling around a few key picks, with Europe at the forefront of the speculation.
The usually well-informed public broadcaster NRK suggested on the eve of the big announcement that the committee this year appeared set to finally hand the prize to the EU, 60 years after the birth of its predecessor, the European Coal and Steel Community, which helped bring peace and stability to a continent freshly ripped apart by war.
The broadcaster also cited the continued struggle for civil rights in former communist Eastern Europe and Mexican Bishop Raul Vera Lopez as top picks, and said it had reason to believe there would be only one laureate in 2012.
In 2011, the prize was split between Liberian President Ellen Johnson Sirleaf, her compatriot "peace warrior" Leymah Gbowee and Yemen's Arab Spring activist Tawakkul Karman.
Commercial broadcaster TV2's list of top picks, also often insightful, was meanwhile topped by American political science professor Gene Sharp for his theories on non-violent struggle that have inspired popular uprisings around the world, including the Arab Spring.
The only name the two broadcasters had in common was surprisingly the EU - membership of which the voters of Nobel Peace Prize host country Norway have twice rejected, in 1972 and 1994.
"The European Union is in the middle of one of its worst crises, but perhaps it is precisely now the peace and stabilisation project deserves a hand from the 'no' country Norway?" NRK said.
Former German chancellor Helmut Kohl, a key architect of a united Europe, has been mentioned by other observers as a possible laureate as well.
Nobel Committee president Thorbjoern Jagland is also the secretary general of the Council of Europe and a fervent supporter of the 27-nation bloc, but recent polls show nearly three-quarters of Norwegians are opposed to their country joining the EU.
If the Nobel winds blow towards eastern Europe this year, NRK and other prize watchers suggest that Belarus human rights activist Ales Belyatsky, sentenced to four and a half years in a prison camp after what the EU decried as a "political trial," would be a likely pick.
A number of activists from Russia, Belarus's giant and supportive neighbour to the north, also figure among the most widely predicted to pocket the prize, including 85-year-old Lyudmila Alekseyeva, who has spent the past half-century defending the same rights in the Soviet Union and in Russia.
Human rights group Memorial and one of its key figures, Svetlana Gannushkina, were also mentioned among possible Russian winners, as was Moscow Echo Radio, described by some as the last bastion of free media in the country, and its chief editor Alexei Venediktov.
Twenty years after the Nobel Peace Prize last went to Latin America, when Guatamalan Rigoberta Menchu took the 1992 honour, NRK also hinted the nod could go to Mexican Bishop Lopez, who has defended the most vulnerable in a Mexico caught in a bloody struggle between drug cartels and the military.
Afghan rights activist and burka opponent Sima Samar and Coptic Christian Maggie Gobran, dubbed Egypt's "Mother Teresa" for her work to help the poor in Cairo's slums, have also been mentioned.
The winner or winners will receive the prize, consisting of a Nobel diploma, a gold medal and 8.0 million Swedish kronor ($1.2 million, 930,940 euros), at a ceremony in Oslo on December 10, the anniversary of Swedish industrialist and prize creator Alfred Nobel's death.
