Olive Branch on Immigration?

Speaker of the House Hastert has extended what seems to be an olive branch, saying that the country does need a guest worker program:

“We're not going to discount anything right now. Our first priority is to protect the border. And we also know there is a need in some sections of the economy for a guest-worker program."

That is new, and is the precise opposite of what many House Republicans believe (I’ve seen numbers ranging from 50 to 70 of hard core opponents of the senate bill). So will Hastert be willing to twist the arms of moderate Republicans, join with many (if not most) Democrats, and thereby force the issue? I’ve been pessimistic, but this appears to be a real change. Meanwhile, even George Will is arguing in favor of a guest worker program.
