OP updated. 

The director for Xenoblade Chronicles X, Tetsuya Takahashi took to twitter again to share brief bit of information about the upcoming title.

In his tweets he revealed that the main script writer for Xenoblade Chronicles X is Yuchiro Takeda, whom you might remember as the script writer for Xenoblade Chronicles. The pair have also worked together in the past on the anime adaptation of Xenosaga.

The main topic of his tweets were about the story, below is a translation of one of those tweets:

“After the ‘basic’ fantasy story for [Xenoblade], we’re having him write a deep sci-fi story this time around,”

Takahashi went on to reiterate that composer Hiroyuki Sawano (Attack on Titan) is in charge of sound, and that Kunihiko Tanaka (Xenogears, Xenosaga, Xenoblade) is in charge of character design.

Takahashi also stated:

“I’ve known Mr. Tanaka for a long time, but this time I asked for his cooperation to bring out the Xeno-ness in the art.”

Xenoblade Chronicles X will be released for Wii U in Japan in Spring 2015, North America and Europe can expect a 2015 release as well.

What does seamless mean ? everyone?, English isn't my first language

Pretty much continuous. You can check with other people as well on that one.

Nice, thank you.

Xenoblade had a story which was far from basic. This can only be good

You know it will be good.

IF you have never played a jrpg this would be an AMAZING place to start IMO. The first Xeno was a swan song to everything that was great about jrpgs when I was playing them as a kid, deep story, interesting fantasty environment, some of the best characters, deep customization (which was once apon a time a MAJOR component of JRPG's that more or less disappeared), and huge Worlds (another thing that has disappeared, but more 7th gen only). All the while improving things like making the battle system quicker by having it real time (where before when you were attacked by or attacked an enemy an entirely different screen had to load which was the battle area).

Xenoblade Chronicles X is exactly where you need to start, because it opitimizes the jrpg experience before it became so freaking watered down. The scale of things might feel a bit intimidating, but only makes beating the game that much more satisfying. 

Cool thanks. I really want the game because I want to explore that world, but it's good to know that it'll be a proper jrpg. Seeing as it'll be my first journey into the genre.

Sounds good
