Someone uploaded the 3 normal battle themes that were included on the 5th CD of the SO5 Ultimate Box.
未確認神闘シンドローム
This arrangement is similar to the '03 Live.
Stab The Sword Of Justice
I have to check the SO2 arrange album to see if there's similarities, but I really like this one.
Like Eriksharp mentioned, we got For Achieve, and the demo version of Confidence in the Domination in the last two TGS sampler albums from Square Enix. I'm really looking forward to the full album in June.
It would be nice if he was able to do a full live concert again for Star Ocean and Valkyrie Profile, though he'd have to find a drummer. Yoshinori is the most recent one iirc, but I do like Nakamura.
