In what was to be expected, British odds-makers have already come up with predictions about the second royal baby's name and gender.
According to a betting agency Ladbrokes, the odds of Duke and Duchess of Cambridge having a baby boy are 4 out of 5, ABC News reported.
The odds of naming the second royal baby 'James' is 6 to 1, 'Arthur' is 8 to 1, while baby's grandfather's name 'Charles' is tied with 'Thomas' with 10 to 1 odds.
As per competing site Paddy Power, whose early favorites is 'Henry' and 'Elizabeth' with 10 to 1 odds, listed Arthur, William, Philip and Charles as other top boy choices, while Victoria, Charlotte, Alice and Alexandra rounded out the top five for possible princesses.
Paddy Power said that they are already bracing themselves for another baby betting bonanza, and added that money was already pouring in "by the pram load" and they expect this to be the "biggest novelty betting market of the year".
