At one of the presentations on the member's cruise they said that this was coming. It is going to be phased in over time.
FIrst will come the ability to view account information such as profile (address, phone etc.) and point balances, transactions etc. This will probably be a couple of phases as each part is added.
Later they will begin to add the ability to update your profile and then eventually points based transactions. Again it is expected to some a bit at a time in phases. I think the idea is to make sure that each part is working correctly before going on to the next feature.
For example the ability to bank points may become available before the ability to make a reservation etc.
It is coming, they seemed to indicate that we may see the first piece late this year or early next year. They didn't really have a timeframe for the whole project.
