The first Nobel to be announced will be the medicine prize on Monday, when the jury in Stockholm reveals the winner or winners around 11:30 am (0930 GMT).
But like every year, most of the speculation is on who will take home the prestigious peace and literature prizes.
A record 259 nominations have been submitted for this year's peace prize but the Norwegian Nobel Institute never discloses the list, leaving amateurs and experts alike to engage in a guessing game ahead of the October 11 announcement.
Topping his list this year is Malala, the Pakistani teen who survived a shot to the head last year by the Taliban for championing girls' education.
Harpviken said she "not only has become a symbol of girls' and children's right to education and security, but also of the fight against extremism and oppression".
But others suggest the prize would be too heavy to bear given her young age of 16.
He suggested the award could instead go to Colombia's peace negotiators or Myanmar's reformists.
Asle Sveen, a historian specialised in the peace prize, meanwhile said he thought the five committee members could give the nod to Congolese gynaecologist Mukwege.
The doctor has set up a hospital and foundation to help thousands of women who have been raped in strife-torn eastern Democratic Republic of Congo by local and foreign militants, as well as by soldiers in the army.
Human Rights Watch said the committee could also choose to honour rights activists in Russia, following the worst crackdown since the fall of the Soviet Union. Activists in Belarus, often described as Europe's last dictatorship, were another possibility, said the group.
