No his wife will not have to fill out a I-864a. Once his income can cover the person he is sponsoring and his household then you would be ok. The I-864a is only used if the joint sponsor's income is not 125% above the poverty line, then he/she can add the income someone in their household.

Look at that form to determine what is 125% above the povety line for your sponsors household 4( you, him, his wife and grand son).
