Nah.
I think they were expecting tantalus to finish twilight princess quickly, maybe end of 2014 to early 2015 similar to the turn around of Wind waker HD and still have Zelda Wii U for holiday 2015.
I suspect - going by the track record of tantalus (that is to say they are mix big of shit and decent), plus this being is their biggest project to date, plus Australia being a poor talent pool for the gaming industry and the high demands of Nintendo, that it took the team longer than expected to churn out twilight princess HD.
It just so happens that Zelda Wii U was delayed as well.
I don't think there is a conspiracy theory or Nintendo intentionally lying
