I thought you saw EVA in store too- saw your post somewhere.
My SA called on Friday morning and I went down to buy. However, I did noticed that they are not displayed anywhere in store in either Hilton or Taka. Maybe you should try Hilton, more personalised service, Taka tend to give priority to "certain" customers.
My brother is in Singapore..Im so tempted to ask him to look for this bag for me...ROFL!
