Amazon.de has a trailer up for the German dub of Tales of Symphonia The Animation. Go to the page for it there, check under the image and click the video to see it. It's mostly Colette speaking with Tenkuu no Canaria by Nana Mizuki playing over part of it, but it's something.
According to an image posted by yinyi982 on Twitter, the anime Tales of Zestiria the X is supposed to start airing this summer. News about the anime is scheduled to be given at Anime Japan this weekend so I'll keep an eye out in case we get anything important.
The English Tales of series blog has updated with a Tales of Berseria piece outlining information on Magilou and Bienfu. This doesn't include the Break Soul info recently, but they'll probably eventually get to that. Copy/pasted below, but screenshots are at the link:
“I suppose you’ll never understand. People can be so miserable. Not that it matters, really.”
Fighting type: Witch
Character Voice played by: Satomi Sato
Magilou is a mysterious woman who introduces herself as a “great sorceress” and “Head of Menagerie”, even though their reputation is for “unlicensed witchcraft”.
She is easy going and rather reckless at times. Extroverted and chatty, Magilou could break the ice in any party conversation, but there’s something sinister about her: something in the heartless things she says to Velvet, and the callous phrases she can sometimes spout, that hint at an evil edge befitting the title “witch”.
Magilou’s chatty demeanour hides veiled intent behind gibberish, jokes and lies. Though she seems cheerful enough, there is something of a trickster about her. Occasionally her heartless behaviour can uncover great truths.
Her fighting style is a rear guard type and she is great at fire and water artes.
In melee battles, she transforms her guardian into various forms and fights in a skillful way!
Character Voice played by: Nao Nagasawa
A peculiar malak with a rather unique hat.
Bienfu can happily be called an eccentric with its characteristic style and habit of saying “Bieeen” and “Bad!”
Bienfu seems feeble but thrives on adversity and lives its life with shrewd attention and strong intent. It seems Bienfu and Magilou may have crossed paths before, though not in good circumstances, as whenever it meets her, it is incredibly fearful.
Unlike many other malaks who do not have their own will, Bienfu shows its personality with various facial expressions.
