"What prompted the decision to make sequel in the world of Symphonia?"
Cheap cash-in, excuse to build off of a story that's familiar (the most successful Tales game ever), and re-use assets without creating entirely new content.
"Are there any plans to continue to bring future Tales games to the Wii?"
The next big Tales game was confirmed exclusive to Wii months ago. No worries. unless it's a cheap sequel to Dawn of the New World
"How many monsters can be active members of your party at one time?"
Up to 3. Emil or Marta must be in the combat party.
