Interesting theory, and quite likely, though the question is why this Pocket Lint didn't publish a Miyamoto interview immediately, and back when the review was still relevant?

Maybe they are gonna delay it and make the graphics all depressing and melancholy.

Maybe they're gonna polish the gameplay, cause it was nothing extraordinary at E3.

So, then this statement was made during E3. Skyward Sword was over half complete since 6 months ago. That's good!

Most likely, if they are only just past half way, the game was revitalized and redone. Likely the game was very puzzel and story oriented, and I think they are tyring to make it more combat focused (thus why Miyamoto said they are making the bosses more challenging).

6 months ago, with a demo, poor graphics, bad connection to the wii, yet all the gaming media seemed to like it. You must be the only one who dislikes it from what I've seen, and I also doubt you've been to E3 at this point

If so, it's an opinion, but don't bring down an unreleased game where we've only seen a small segment from more than 6 months ago...
