Final Fantasy XII and Phantasy Star Universe. I will getting both of these and most definately will be playing them A LOT. PSU in particular because of its online aspect paired with the 360 will be great, just like the good ol' PSO days! :D

I'm especially interested in FFXII as it looks similar to Skies of Arcadia and FF Tatics... I'm looking forward to exploring the world there with the airships! :P
