I think the seventh will be a girl because most of the seven will hook-up with each other. Its just a hunch, but here goes. Annabeth-Percy- already together. Piper- Jason- getting closer. Leo- Hazel- just a guess. Frank- and the seventh demigod. Also the girls must balance out the guys, another guy will throw off the balance, plus boys get way too much credit.
