There were some rumours on the GGL enhancement thread, but no firm details. I guess it's a case of burn now if there's somewhere you want to go it works for you as you know the current rates, or wait and see. Not much else to do.
Interesting that there are a couple of Avios promotions right now - the European bonus, plus greater advertising of the Amex referrals and the increase in what you can earn from that. Maybe that's to soften the blow.
