As you appear to be in the 'inner circle', do you know if the FX surcharges will be waived on the World like the they are for the Platinum? This is the biggest selling point for me over other 1:1 earn MC/Visa cards (even the Citi Signature for free). I easily cover my current $99 annual fee with the FX savings (if you spend more than AUD3350 on FX in a year, which I can do in a single trip with flights, hotels etc).
Sorry, I wouldn't know.
From a product design perspective, it wouldn't make sense to not waive the foreign transaction fees. There needs to be an incentive and many good reasons for us to upgrade and pay a higher annual fee.
