You do realise there is technology on the show floor for journalists to try out and report on? E3 will never die.
I don't see how that changes things. Video game companies need no live show anymore (at least not one they don't fully control in their own terms), and being overshadowed by bigger games after all of the expenses of going there is not really an attractive prospect. Once videogame publishers and devs stop going there, will E3 be even profitable to organize? If I recall, they are the main show, most people who go there pay to see the games, not the hardware. And even if it stays profitable somehow, would E3 even be relevant for most people?
You know it deserves the GOTY.
