Just as a point of interest, it looks like virtual events are becoming the norm. There's a fairly good list accumulating for vendors attending E3 in June.
Hopefully that means we'll be getting lots of cool updates on upcoming games, tech and other fun stuff.
So far, the following have confirmed they'll be holding presentations during the con:
BANDAI NAMCO Entertainment
Devious Eye Entertainment
Warner Bros. Games
XSEED Games / Marvelous USA, Inc.
