Is it a delay if it never had a release date?
Zelda didn't have a release window until a few weeks ago, and I don't see any reason it will be delayed yet. I'm not sure about GT5 specifics but I don't think it had a release year until late last year when it was said to release next year (2010)---- Edit, am I wrong about this? was it meant to release in 2009 for Japan?
Until one of them is confirmed to not release in 2010, then neither has been delayed as far as the public are concerned. If you are talking about development delays then I don't think anyone can doubt GT5 is the more likely candidate for them (not that we will ever know about them)
