I really hope that since they're taking their time with this one (unlike PW1 and PW2 which were just a year apart) the game will be of much higher quality. I also disliked PW2's story greatly. Really hope they stick to canon story while maybe adding some sort of filler material that doesn't go full on bullshit like PW2's.
Hopefully it gets released to the West on all the announced platforms (PS4/Vita/PS3) be it physical and/or digital. I really wanted a localized version of PW2 for the Vita so hopefully Bamco will give PW3 Vita a chance in the West.
