We might get these in the expansion pack. I think this is just a small sample of what the real PSU is, its possible that theyre will be new PA's aka Heaven Punisher, Gal Wind Attack, J-Sword attack, perhaps even the olga flow thingy. Hopefully this all will happen eventually. -.-'
Sonic Team is not
releasing an expansion pack to turn PSU into PSO.
There hasn't even been an expansion announced yet - and no, that "Ambitions of Illumines" poster hidden on PSU's website is not the teaser-art for any expansion. It's the teaser art for PSU Ep II, of which five chapters have already been released on the US/EU servers.
