I wish I was as optimistic as the others in this thread.
We just had an event which was hyped for months and yet the big announcements with regards to third party from this event was.... meh.
They showed XB2 which looks like it won't be out until 2018 but had trouble showing other games in development set to launch in 2018? I don't believe it.
Capcom had so many potential announcements for Switch. AA, MH and even SF could have been announced, yet we heard nothing from them. Even Level 5 was absent.
SE had their DQ announcement but that was old news by then and Heroes pack-in is not some exciting 'system seller'.
It's not that people are being optimistic as much as you are being pessimistic.
