It's a strange situation - In one sense, the TV deals should be the same but as things stand, the women's game doesn't have the same appeal as the men's so from a commercial point of view, it makes no sense.
The way to make the women's game more popular is to televise it and reach a wider audience. Then in future tournaments, it'll have more commercial value.
If FIFA wanted to put the men's and women's tournaments on an equal footing, they'd be hosted together and everything - sponsorship, TV rights, stadia, etc. will be combined. Like they do in Tennis.
