The next Phantasy Star Online to have melee weapons combos and quick weapon switching similar to Bayonetta... Not as deep, but just a few 'demanding' moves that need slightly more button inputs then the normal 'X,X,X' or 'X,Y,X' type moves.
I think if they could get the addictive combat of Bayonetta into the online social atmosphere and OCD item/weapons/rare collecting frenzy of Phantasy Star Online I would never have to play another game again.
That is all, discuss!
