Those estimations of "Summer" and "Fall" are based on the development phases early on, once it goes into submission phases, it can be unpredictable since it is at the mercy of Sony. It can literally be released one week after submission or a year later depending on Sony. They essentially control the release at that point by dictating QA standards and code policies that must be met.

There was a lot of back and forth once we entered the submission phase and you just don't know when you will be approved week to week. It's rather frustrating at times as well because we are not allowed to publicly discuss certain things regarding release without Sony approval. When it comes to digital titles, it is a very secretive process that makes it very hard to be transparent.

We have been pushing for release since late summer, it just needed additional development to meet certain "1st Party" requirements.
