The way I see it, companies fire people for reasons beyond the employee's control all the time. And I'm sure you'll be considered an "at will" employee, so they could technically fire you for any reason that isn't blatantly discriminatory. So why feel obligated to stay if you get a better job offer elsewhere, even if you just started?
I agree with what other posters are saying. Take the sure thing and dip if you get an offer from the bank.
