This was interesting:

"Touch ID- For the first time, you’ll have the option of using Touch ID to sign in to third-party apps — there’s no need to enter a password. Your fingerprint data is protected and is never accessed by iOS or other apps."

Will this be used significantly by developers?

It depends. For secure applications? I doubt it; fingerprints is identification, not authorization. Bank apps and the like won't consider it secure enough.

yes, i think so. Any app that has a password on it now will likely "upgrade" to this. Prime examples being finance apps.

Yes.
