After thinking about it more, the conference wasn't that bad (but it wasn't good either).
Boundless, Detroid and Gran Turismo we great (and in the latter case long) announcements.
And the new stuff we've seen from Horizon, Uncharted, Dreams (!!! Oh my god, this looks amazing) and Wild (really like the looks of it) were great.
Still, some big announcements have been missing to make this a good conference, but the E3 show had enough of that already.
