Wait, WHY? City of Ashes Filming this Fall

It was just announced yesterday that City of Ashes got the green light for filming.  The cast will be the same.  While I like the series, this is a gutsy move!!! I'm not so sure that this is going to be the next big franchise.  The Host was supposed to be the next Twilight but that was a fail.

I can't help but think this is so stupid.  Why wouldn't you wait until after City of Ashes comes out until you make a decision? Hubris could be your death...
