I think he was more looking at Minecrat that continues to rise in charts.
Ahh potentially. I saw Gundam at the top of the chart and I came to think that that was what he was referring to with his comment.
IIRC, when they were still developing the game and promoting it in vague ways, Takahashi talked up how he felt that Xenoblade was light on story and world details, and he wanted to push that further with Xenoblade X with a richer world and deeper story. After the game came out and everyone said there was even less story and more MMO-ish content, he's apparently now saying that they spent too much time making an open world on new technology, but now that they have the tech down, they want to go back to making a more story-rich experience for the next title or whatever. Same old shit.
Well they definitely made a richer world than Xenoblade, and they definitely flushed out a lot of the side content to a much higher degree and quality. But the story is nonexistent and largely inconsequential.
Do you happen to have a reference on this one, not that I have any real reason to doubt you? I want to say I remember them talking about the content/side-content bulk and world rather than the story pre-release.
And well, if XCX flops, it may send the message to Monolith to make things more like X1 with X3. But XCX underperforming may also retain Nintendo from investing more in the IP.
Xenoblade is Nintendo's core-jRPG franchise at this point. Its nothing grandiose like Final Fantasy, but I wouldn't be surprised if the series grows up (on a healthier platform) to Tales-level of successes at home eventually. The west may well drive Xenoblade past Tales even with this entry on a WW level comparison (given the later's weak performance outside of Japan). Its obviously not going to reach anything much more than that any time soon, or on the WiiU for that matter.
If they felt this entry didn't quite meet expectations or "needs another shot", they'll port it like they ported Xenoblade (or find ten different ways to sell it to you again). Its definitely a mark associated with Nintendo now, though.
