That headline is short for "The Witcher 2 Character Development Developer Diary". Yes. If you'd like to watch some guys from CD Projekt talking you through all the different ways you can develop protagonist Geralt, and all the different ways you can play and he can fight, they're waiting for you right after the jump.
The Witcher 2 is going to be great. We know this because ever since Jim played the preview build, we here at RPS have had to put up with his near-constant pining for the finished game, which sounds like a cross between a lupine whimper and an Amiga 1200's boot noise. May 17th can't come soon enough.
