More sources have apparently leaked Sony’s first-party line up for the PlayStation NGP, with four first-party titles set for the system’s holiday launch.

The four first-party titles are:

Uncharted
Smart As
WipEout 2048
ModNation Racers.

Resistance is supposedly launching in early 2012.

The source also claims that the previous rumours that NGP will launch in North America before Christmas are true.
