I'm thinking of applying for the next round.
Even if your product doesn't suit the local market, and even if you don't plan on keeping a presence in Chile after the six months is over, consider this: you'll be spending lots of time around hundreds of other interesting people, all of them getting paid with no strings attached to work on an idea they're passionate about. In a completely unfamiliar country. It's a grand experiment in anarchy, I think, and who knows what will emerge on the other side...
I'd consider going to Chile even if I don't make it in the official programme.
