Are you trolling? Haha, calm down, man.
DMC and Bloodborne are both very big series, would it really have made sense to announce them when half of Sony's audience was asleep? After this year's E3 event, it's pretty apparent that they're saving all their announcements for PSX. A disappointing 2018 for Sony is highly unlikely because you have GoW, Spiderman, Detroit, Days Gone, Yakuza 6, SoTC, Ni No Kuni, Dissidia and possibly TLOU2 all releasing in the year.
