I do not work for Bose but have been in this forum a year or two and based on Bose's past behavior 1. They don't pre-announce firmware or matter of fact anything
2. Most of the time they don't tell you what they are working on (the exception was the big study that went over Active Noise Cancellation [ANC] and the QC35ii with firmware 4.5.2) and in the rare instances you know they are working on it, you will not find out if the feature/fix will show up in the next firmware release and when that release will be
3. They are very happy to accept feature enhancements or additions but you will not know if they have implemented it until the firmware is released.
4. You can not use previous firmware release intervals to predict when the next one will be.
