I was not that shocked that it was not going to happen this year. Yet it was. To me these is just another blow that E3 is not that mainstream event that It once was. I just think that E3 is an out of date relic that was going to be thing of the past very soon.
Do i think it will ever come back in the future? No. With so many of game companies doing their own mini event throughout the year & can do it on a much cheaper budget. E3 was just on life support & with current technology to just put on a show on the internet. Companies just come to a decision to make there own show case. They can just do things better on a cheaper budget without risking a total failure.
