In order to make BioShock Infinite "even more extraordinary", the decision has been made to postpone the title until early 2013.
The news was followed up by a rather extensive letter from the game's primary creator, Ken Levine, from Irrational Games. He said "When we announced the release date of BioShock Infinite in March, we felt pretty good about the timing. Since then, we've come to realize that some specific tweaks and improvements will make Infinite into something even more extraordinary.
"Therefore, to give our talented team the time they need, we've decided to move the game's release to February 26, 2013. We wanted to let our loyal (and very patient!) fans know this as soon as possible."
Levine also confirmed that BioShock Infinite will not be making an appearance at this year's E3 in Los Angeles, or Gamescom in Germany. "The next time you see our game, it will be essentially the product we intend to put in the box," he said. "Preparing for these events takes time away from development, time we're going to use instead to get the best version of Infinite into your hands in February."
This news will be seen as a blow by the franchise's fans, but it does mean that the end of this year will have one first-person shooter less to occupy gamers. It may also help to boost sales for the title, if there is less competition around it's new release on the 26th of February, 2013.
