At the Squeenix shareholders meeting Wada mentioned that while no new games are yet planned for the Mana or Saga series, they do plan on some ports.
I know nothing about the SaGa series, so cannot comment on that.
But what I can say about the Mana series is that this is a great idea. I still feel Dawn of Mana may have fared much better had it been released on the Wii instead of the PS2 (during the PS2s death) and had it utilized Wii MotionPlus swordplay like Skyward Sword. Could this be what they have in mind?
Probably not. Probably just a port of the iPhone remake of Secret of Mana to Virtual Consol or 3DS. Which I still would whole heartedly welcome since though the updated graphics are gorgeous, I have zero interest in finishing the game. I gave up mid-game due to the constant frustration of trying to use the touchscreen on the iPhone as a directional pad. Ported over to the 3DS or Wii's Virtual Console would solve that annoyance.
Of course, if these ports sell well, I'm sure we could finally expect to see actual new games!
