Again your opinion. To others E3 is all about this year. To others it is all about the future. To some like me it is all about a balance. So I would 100% agree that MS won this E3, but that is just me. As for Hololens what they showed of Minecraft excited a lot of people. Just saying.
So if Sony hade revealed a PS4 in the form of a handheld at $200 and gave every PS4 owners 5 free games they would not have won E3 if those things happened in 2016? Also gamewise Hololens reminds me of Kinect, a lot of big promises but in the end it didn't add anything to gaming. In that regard VR is more promising, something Sony hade at their conference but chose to let people try out for themselves on the showfloor instead of dwelling on it to much. That cool Hololens Minecraft demo? Yep nobody could try that out for themselves, all their was on the showfloor was a stage were you got to see arrows pop up and a table with a 3D master chief. Again cool tech, but not interesting for gaming at all.
