Oh that's interesting. Plus there's that Poetic Justice achievement, I wonder who the ally is. I'm betting the ally will be unlockable after beating the game.
Either that or they refer to 'ally' as one of the other players in your team.
It might also halfway confirm Astarte being in this.
People have seen Yoko in a corner of one of the screenshots,

hmm, if Harmony of Despair sells well enough, then the PS3 community may get to enjoy it too! I know a lot of ps3 only friends that want this so badly but had bad xbox360 Rrod experiences. Xbox360 is very reliable as long as you take care of it, but I admit it's the most fragile console against heat.
PS3 owners will still have to wait about 6 weeks before Konami even starts to consider porting this, but some have a theory they will anyway just because they would miss out on making more money if it remained exclusive to 360 forever.
