I sincerely got nothing to lament and fully support Geoff and whoever joins him in not being there anymore. E3 is just not what it used to be, the ESA keeps being a joke of an association. E3 is not gonna die immediately, but this 2020 for sure we will see the flood of youtubers and influencers filling up the event like never before in hopes for keeping his relevancy.
I truly hope the Nintendo thing not being there also becomes true. Absolutely nobody needs E3 at this point. Big publishers know they can do stuff whenever they want, indies get lost in the ocean of announcements, it's a lose/lose situation for everyone.
Little Edit: For everyone missunderstunding Jeff's tweet, look it this way. E3 being treated as "Gamer Xmas" would be like Santa coming on December 25th to your house and tell you all the good things you MIGHT get in an undetermined amount of time. Now just be a good patient little boy until your "present" arrives in 5 to 12 more months (if you are extremely lucky your "present" didn't get stuck somewhere).
