This might be related to the work being done on https://issues.civicrm.org/jira/browse/CRM-16555 - I have been able to reproduce this issue in the demo site with slightly different results than in our 4.6.7 dev environment. To reproduce:
1. Link a price set to a contribution page
2. In 4.6.7 enable multiple payment processor options on the contribution page (one of them being the default)
3. Go to live page > default payment method is selected, but no payment form fields are visible
4. Click on a different payment method, then click back to the default - payment form fields become visible > looks like the system is not recognizing the default payment method as a selection and is requiring the selection action to show payment form fields
I was going to mark this issue as trivial because in 4.6.7, by removing any of the payment processor options as the default and forcing the user to select an option, form fields appear according to selection which appears as normal behavior.
The problem is, in 4.6.9, regardless of whether there are multiple payment processor options enabled on the contribution page, no payment form fields appear when you go to the live page, so there is no way to perform the selection action that the system is waiting for to show the payment form.
