No, why and what does that matter? Not everyone that would like to see a game released that they'd happily buy HAS to pledge up front to be relevant in commenting on the fund raise effort.
FYI, I likely will pledge before it's up, but how much I pledge will depend very much on what happens between now and then.
I back very few projects in general, but that doesn't mean I am against their success. I'm also in the middle of a very - for me - expensive move (overseas), so it'll be a flight, a few weeks, and a bank account change, before I back anything further once I get settled in again.
