(CNN) -- A day after Saudi King Abdullah announced greater political participation for women in the future, some Saudis questioned just how big a change may really be on the horizon. Some women's rights activists who were initially elated by Sunday's announcement said they were feeling disappointed because the changes do not kick in immediately. "We don't really think now that we've been promised a real right," said one. But a member of Saudi Arabia's Consultative Council called one of the changes the king announced "hugely important." King Abdullah announced two changes Sunday, which would be historic for Saudi Arabia. He said women will be allowed to serve as members of the Shura Council, the Consultative Council that advises the king. Its 150 members are appointed.

While the king did not use the word "vote" in his remarks, allowing women to take part in the nomination process would amount to voting within @placeholder's system.
