Squenix have announced a new SaGa game, possibly as part of Jump Festa, along with a load of FF15 news but as Final Fantasy is dead to me, I'm focusing on this instead.
So far there is fuck all on display and what they do show leaves a lot to be decided. At the moment this sadly doesn't look likely to be localised. Also Minstrel song and its non Pal localization is coming to PSN as well as part of a 25th anniversary edition. Oh and DDS translation are currently putting the finishing touches to the SNES original if you really can't bear the voices in the remake.
Edit, there is a PC offshoot called Imperial SaGa, which looks horribly like Freemium rubbish to my eyes, and I don't think this is going to be localized either.
