Rumors are out there, on Neogaf, claiming that Sony's big title, for the fall, The Order: 1886, has been delayed until February 2015.
If true, this would leave Driveclub as the only big First Party title, from Sony, on the PlayStation 4. Sony, thus far, is remaining quiet on the subject. With their E3 Press Conference only weeks away, they probably won't spill the beans on anything before then.
UPDATE: Sony confirmed in a blog post the delay is true.
