More Uncharted 2 DLC incoming?

Uncharted 2 voice actor Emily Rose tweeted of her involvement in further Uncharted content yesterday, leading to rampant rumours of everything from Uncharted 3 to PSP conversions of the PS3 classic. The explanation is only marginally less exciting - according to Kotaku, a Sony spokesperson claimed that "Now that Emily is just back from filming Haven she will be working with Naughty Dog on some DLC content."

If said statement is accurate, this will be the first of Uncharted 2's DLC to feature further voice-work, since the title's release in October 2009.
