I sympathize with your frustration and agree with your points. The original press release clearly said that all localized versions would be released by the end of Q3 (September 30). If there are delays, GS should make an announcement (and apology).
I also don't see why everyone's keys are not immediately upgradable so that the INT version can be used, if nothing else for learning the new features and migration steps.
