The APAC devices have different internal part numbers, so people in Asia (China, Taiwan, Japan, etc.), don't have apps available on their store if the app does not have support for APAC devices. Once developers begin to rebuild with 1.1.2 (or your app gets converted as recently announced), apps will begin showing up for APAC users. I don't think you'll need to lure anyone back--users in Asia have been disappointed in the lack of apps available to them, so they're anxiously awaiting more apps!
