Well, since I spent the last hour and a half thinking about this, I should comment about it so I can focus on other things today :lol
Lets see, a direct sequel to Symphonia is doubtful, only direct sequel in the series is Destiny 2 and that just has you-know-who to play from Destiny cast. Symphonia 2 (as a name) sounds like trying to lure Nintendo fanbase again in the West. Not to mention there is a somehow sequel, Phantasia, and changing the cast again plus the events in the game (to Ragnarok War for example) would probably mean another different title, not Symphonia 2. This isn't a strong point, sure, but lets say other options sound far more likely than this one.
Also, I haven't seen anyone in IGN guessing previous Tales announcements, last time (June last year) we only knew about them (Destiny Remake and so) thanks to early leaks of Dengeki or whatever magazine it was. At this rate, when an announcement actually happens, everyone will be fed up just on rumors...and I'd have to remember everyone that the only tales announcement in the last 12 months is a Fandom game.
Trying to give some more weight to this, maybe Namco Hometek is making this game on their own. You can count me on the Tales haters Team the very first moment something like that is announced :lol (you can bookmark this...). Anyway this rumors looks easily more feasible than Jeux-France one. I go with 'nah' but I can see it being true, and I'm sure there will be 200% more yaoi fanfics if this is true
Btw, we still have two batches of names to be used:
2006-108290 Tales of Innocence
2006-108291 Tales of the Innocent
2006-108292 Tales of the Manes
2007-016169 Tales of Valoria
2007-016170 Tales of Strife
2007-016171 Tales of Vesperia
PD: WHAT? SONY HAS ANNOUNCED A PRICEDROP? HOW DID I MISS THIS? Tales makes me blind or something....:lol
