It's not uncommon for something to get pushed over after a while, solely because the company has no faith in it or other, more valid reasons.
One of my least favorite examples is Robotomy on Cartoon Network. After being developed for around 2 years (on ten 15-MINUTE episodes), it was given very little advertisement, all episodes were burned off quickly and there were practically no reruns before it was removed from the site.
This is also rather sad so far, but they might give it a bit more of a push during the next 2 weeks. Though that's still crap treatment for a 3 year wait, it's better then what Nigoro got, who got no notice of his own game's cancellation.
