I would reckon that Sony would have another presentation during the E3 showing off everything again to the public. Perhaps with concrete release dates also for the titles that are still listed as just 2014.
They have already announced a localization for most stuff they are going to publish in Japan this year. I think they'll talk about it for like 2 minutes, announce Ratchet and Clank Collection and some PSN port, mention Remote Play and PSNow and go to the PS4.
Last year they announced Freedom Wars and Destiny of Spirits some days before their E3 conference. They could do something like this again.
The question is: will we get that rumored Infamous game or not? I'm starting to lose hope
