No, i want Baten Kaitos 3 next.
Isn't Baten Kaitos also Namco's property? It would make that game as difficult to make as a new Xenosaga.
Then again, they know that Monolith Soft has made a name from themselves around the world, and considering the Xenoblade Chronicles came out in Japan in 2010 and X came out in 2015, it's probably 2020 when the next Xenoblade, or whatever Takahashis next project will be. It'll take a while, so I'd gladly take at least Xenosaga HD Trilogy while waiting for the new game, so scratch that itch for Monolith RPG. Even more so, when considering only Episode II of Xenosaga was ever released in Europe.
Then again, Nintendo and Namco have quite good relations, so who knows. I ask it in E3 Miiverse community every year, so hopefully they have at least seen it. As for Xenogears, there's some rumouring that Square-Enix and Nintendo have better relations now that in ages, but I still doubt there will ever be Xenogears remake. I'd take a PS1-port release for Europe, but doesn't seem like it's happening anytime soon.
