I somewhat feel this way also, because it seems a little far fetched for them to be able to constantly take in feedback and Implement them as they go along, and know for sure exactly when it will be finished.. They have to at least have cut off the taking in of new requested features at some point and just start focusing on smoothening things out/fixing bugs in order for it to be done by a certain date.. I honestly feel like they're probably done with W10 already and just giving us their old rough & rusty builds to make ppl feel like they're apart of the progression...but I'm probably wrong
