I've yet to try online but yeah ive noticed the new run since be booted it up. My bro being the bigger fan was like "WTF??? New running animation!!" I noticed it too when i played. The running animation to me seems more anime-ish to me, not too girl. The sword and shield running animation is cool too.
The universal pp system is just being that you have all your weapon techs linked to that one gauge in PSP2 when in PSU, every weapon has their own PP gauge for weapon tech.
Have you gotten Double Sabers yet in the PSP2 demo? That weapon is godly.
