First up new SO4 stuff!
http://www.gamekyo.com/newsen29145_star-ocean-the-last-hope-new-screenshots.htmlFrom what I've gathered from GameFAQs -
*Sidestep - The sidestepping mechanic from SO3 has been enhanced/upgraded to become a big part of the battle system
* Jump - There is a Jump command now and character's will have unique jump abilities, like for some jump will be a quicker sidestep, some will jump higher, etc
*New characters are Faize Sheifa Beleth (elf like chick) and Lymle Remli Phi (token kid character)
