Since there seems to be discussion about some specific lines of the article concerning handheld release: by reading it, that's just an hypotesis based on the upcoming 3DS lineup Trev will post tomorrow on his site. The source just makes the assumption that, due to the lineup being much better for 3DS than Wii U, the home console will be released earlier over here. It's not the source telling to Trevelyan that it's going to be like that (as I've read earlier), just his idea (personally, I think it's a wrong assumption, because NX handheld would represent the entry point in the NX family; the NX home would follow, representing an alternative with higher performances and prices for those who prefer playing on the TV screen). In the same way Trevelyan thinks Zelda U/NX as a launch title confirms NX is a home console (which is, again, wrong IMHO since it's not such a deciding factor). Again, it's an hypotesis. The rest of the article, going by what's written in it, is a report of what it was referred to him as "fact" (brackets for now since it's still a rumour).
Hopefully that's a good clarification of specific parts of the article.
