I don't see any issues with Apple releasing a new version of the AirPod's this early. It's not like your current AirPod's get any worse by them releasing a new version, so does it really matter? Unless you have some urge to always have the latest and greatest there is no reason for someone who have bought rev1 to feel bad for them releasing a rev2. Of course there will be some improvements, why else would they release a new version. Sure, you might end up wanting what ever improvements they have done but it doesn't change the fact that you would still be stuck with your AirPod's regardless of whether Apple releases a new version or not. I doubt there will be huge upgrades. I bet they have done something with the manufacturing process in-order to address the demand. And perhaps they have done something in-regards to controls and obviously they moved the charging indicator to the outside of the case instead of the inside.
