Nobel Prize for GPK?

I have been hearing this since the first news of peace accord. That seems little fortuitious to me. If the "Prize" were to be awarded it cannot be only for GPK. Let's look at some history from Nobel sitg:

1973: The prize was divided equally between: Kissinger, Henry A., USA, 1923-.Former Secretary of State; and
Le Duc Tho, North Vietnam, 1910-1990. (Declined the prize.) Jointly negotiated the Vietnam peace accord in 1973.

1978: The prize was divided equally between:Al-Sadat, Mohammad Anwar, Egypt, 1918-1981. President of Egypt; and
Begin, Menachem, Israel, 1913-1992. Prime Minister. Jointly negotiated peace between Egypt and Israel.

1993: The prize was divided equally between: Mandela, Nelson, South Africa, 1918-. Leader of the ANC. and
de Klerk, Frederik Willem, South Africa, 1936-. President of the Republic of South Africa.

1994: The prize was divided equally between: Arafat, Yasser, Palestine, 1929-2004. Chairman of the PLO; and
Peres, Shimon, Israel, 1923-. Foreign minister of Israel; and

Rabin, Yitzhak, Israel, 1922-1995. Prime minister of Israel. Awarded for their efforts to create peace in the Middle East.

So is there not a bias or misunderstanding of peace process in thinking GPK is the one deserving, but not Prachanda?
