Posting on the official forums, Bell first confirms players shouldn't expect the game in the first half of the year. He mentions that the game has already started the Quality Assurance process, and that the team has planned for at least seven months to minimize bugs and maximize polish. This should be welcome news for those who remember the original v1.0 release on consoles.
A few days later, while responding to the question of when pre-release details will be available, Bell says that the ”current guess is Septemberish”. It's a suitably mysterious answer, especially when he mentions that the team is ”a bit behind on GUI and Career".
