I mean the thing is we already know what is happening in 2019 in terms of games....
Edit Forgot Ghosts as well... damn still much to come.
So we can see that 2019 is pretty much set in stone and no need to talk about these games at E3 or announce games new for 2020 as they'll be PS5) as Sony have learnt that got them burnt before when trying to match MS for earliest announcements (I think this is the change in attitude). I think MS will go back to E3 showing logo's etc but if they dont mention next gen, I think thats lost on the audience.
Layden actually stated they wouldn’t have enough new stuff to show, so they’d rather back out instead of delivering a disappointing show...we’ve all seen X018 a few days ago.
The more I think about it, the more a big 25th anniversary PSX in December, with possible PS5 announcement, seems to make sense. PS4 was announced in February, so what difference do 2 months make?
