sbiddle:The biggest issue is getting Google to changes things, and the roadblock that already exists with Mastercard and Visa both loving Gemalto's NFC solution (which is what Auckland transport are using).
Yes agree with you on Google but at the moment they are allowing parallel UICC implementation with Google Wallet. Apple will also be interesting. But to control it in typical Apple fashion they will need a lot of ecosystem pieces under their control which will be a challenge even for them.
As for Gemalto, they should come into line with the SIMalliance specification (& will be driven there by mobile operators) although any trial may use a 'pre-standards' solution.
