Doesn't them still not having voice commands for these countries kinda proves Penello right? They are able to release it anyway now because kinect has been dropped, otherwise it could have been delayed even further...
Also, localization doesn't mean just voice, Ms also needed to trade xbox live servers to Azure servers, so games that rely on cloud compute behave the same on each country xbone is launched officially.
I don't think anyone could look back at launch and say they were being held by poor production rates, so either way, I don't see how this news makes previous claims not true.
