There are several options for funding on the table, which one the group goes with depends greatly on the final terms settled. I've seen that in cinema before, a movie producer needs $80 million, so he goes out and finds $200 million potential, but with each segment having various terms. "I'll put in $10 million if you can get this actor in it" along with "I'll put in $15 million if you get this screenwriter" and so forth. He gets this larger potential pool and then negotiates. He will not get every actor, screenwriter, director, cinematographer which is asked for, so he will not get the full potential pool. That is why he goes for a far larger pool than needed in the first place. As he negotiates for various bits, he secures, or loses, various promises of funds.
So, when I say "too much in the air" I mean just that, it depends on how the negotiations go for what is the final arrangement.
