Developer Naughty Dog has revealed that sales of stellar sequel Uncharted 2: Among Thieves have vastly eclipsed those of its predecessor, Drake’s Fortune, noting the universally acclaimed title is currently “exceeding expectations” at retail.

“I would definitely say it’s exceeding expectations,” the firm’s creative director, Amy Hennig, told IndustryGamers.

“Being in the industry for a while you learn to try to manage your expectations because you’d rather be surprised with good news than disappointed. It’s a tough business, but from the early numbers I’ve seen getting reported back it’s exceeded any estimates we had internally, and it’s certainly outsold the first game by many, many times. That and the critical reception so far has been really gratifying.”

Elsewhere, Hennig also divulged that fans can expect the first batch of downloadable content for Among Thieves to arrive before 2010. Apparently, the company will be offering a mix of both free and purchasable goodies.

“Without going into specifics, it’ll involve new maps, new characters, things like that. Some of it will be free of charge and some of it will be purchasable. We’ve got a lot of people on the team working on this stuff, some really cool stuff that people will be excited about,” she said.
