For the most part, I only play a single (sub-)genre and nothing else. The E3 was a nice event to get up to speed on anything else. I don't care enough to keep up with all these different presentations and announcements if they are not bundled together. I'll kinda miss it.
They're still bundled, it's just fans doing the work to put them all in one place. The spectacle was cool but E3 was always going to die once the internet became widespread.
The announcement was that they cancelled E3 this year and a lot of people speculated it was done for good, this is the first time we got official conformation.
