T2, BioShock Franchise Still "Really Important," Infinite sells 11 million copies

[Yafea]

2k talking about the importance of Bioshock before E3, a new game announcement incoming???

Bioshock 1: 2007.
Bioshock 2: 2010.
Bioshock Infinite: 2013.
Bioshock 4: 2016???

There's a pattern of having a new Bioshock game every 3 years.
