Link, please? To the original article, too. (Surely the wiki of which you speak cites its sources, yes?)
Everything posted at wikia.com needs independent corroboration. Battling editors, things changing day after day. Perhaps the most unreliable source anywhere.
Point a favorite search engine at "Nomura said" for a whole slough of misquotes over the years. Years ago it became so bad that by default "Nomura said" statements require supporting links anymore, so thanks for taking the effort. Without them, most will presume you're talking out of your hat.

The KHWiki is weird, which leads to it being untrustworthy. An example is that they would not change one of their articles on something (sort of a spoiler for this board), even though a sourced Nomura interview contradicted it. Until KH3D straight out said it, then they did. I don't have an issue with them not wanting to use interviews as a source (though, I'm pretty sure they have elsewhere), more that they blamed the occurrence on a fan theory instead.
But ignoring that, I've never seen an interview that said what that page says. And I can't seem to find one now, either.
Just one that says that he hadn't planned on making a Final Mix for KH2, but that there was a demand for KH2 with english voices in Japan. His staff said that there was no room, however. (Famitsu '06, dunno the month)
As for the non-JP release of the FMs, it's never been clear to me if that were Nomura or Sony's decision.
Better sales, lolNomura
I mean. I guess. FM2 sold about a quarter what KH2 did in Japan. Re:CoM sells 3 times that in NA and is considered a failure.
The fact that they even needed to make an FM+ to fix the game is Nomura's fault, though.
Not exactly, he was willing to move on to the next project. Glad he didn't, personally.
