Kojima Productions has said to expect a fully localised English version of the Metal Gear Solid: Peace Walker demo "soon".
The 150MB sampler is already available in Japan.
Speaking on the KP podcast, reps said that the English version would include voiceovers from the usual suspects - David Hayter, Tara Strong, Chris Randolph and so on - along with subtitles.
Peace Walker is Hideo Kojima's latest baby, and picks up the series' story after the events of Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Portable Ops.
Check out our recent hands-on preview to see why it's one of the best-looking prospects for the PSP in 2010.
