Grab as much as you can, when you can before 2015!
Even if you travel overseas, unless you pay by foreign cash, our weakening ringgit will cause havoc with your wallet!

My take and prediction, our local ADs are essentially screwed as far as we are concerned as the WIS and collectors will start seeking out grey dealers and 2nd hand sellers (that don't factor in GST). Those that do still buy from ADs will be the Limited Editions and special orders that are exclusive to ADs. Even then a lot of us will end up buying 2nd hand or even grey resells.
My prediction is that from 2015, the retail AD growth segment will have to be tourists that can re-claim GST. I dunno how badly this will affect them... But then if SGP can survive and thrive on 7% GST...
All IMHO and speculation on my part.
