Janco Partners analyst Mike Hickey says Irrational Games’ upcoming first person shooter, BioShock: Infinite has the potential to move a lot of copies, and that it certainly can and should sell around 5 million units, amassing 2K games a $221 million in sales.

He reckons the game will outsell BioShock 2, the 3 million seller of last year.

We certainly think the game does seem to have the potential to sell that much, if not more. Here’s 10 reasons why we think you should get excited about it.

The developer of the famous Bioshock series, Irrational Games, has revealed that their upcoming title, Bioshock will have more varied kills than Bioshock players are used to. “There’s a famous saying: ‘When all you have is a hammer, everything looks like a nail.’,” Levine said while talking to the PlayStation Blog.

“That’s kind of how it was in the original BioShock. You walked down a tight, restricted corridor with Electrobolt in one hand and a shotgun in the other, and that was an effective way to deal with most of the enemies.

“One of the reasons we wanted to really expand the scale of the environment in BioShock Infinite and the number of enemies was to create situations where certain tools would have clear strengths and weaknesses based upon what you were up against.

“There is no perfect combination or an ideal set of tools, and there’s going to be a larger variety of weapons and powers. We wanted to show that even familiar weapons like the shotgun are not always the right tool for the job. And the sniper rifle-unlike BioShock’s crossbow-actually has a specific function because of the extreme scale of our environments.”
