Who said Titanfall 2 and Destiny 2 were Q1? Titanfall 2, if anything, is looking like it'll be end of this year. Destiny 2 will be September 2017 if we're sticking with the September trajectory the series has been accustomed to with the release of Destiny 1, Taken King and the next expansion (I swore I saw a hint around here it was planned for September time again).
Sony has delayed virtually every single first party release at least once this generation, it would be more surprising if something came out when they said it would. Zero reason to ever believe a relase date they put out, hope people keep that in mind for E3.
