If David and Dan wanted to hold off information for future seasons, they wouldn't have approved the confirmation of Rhaegar as Jon's father (which wasn't expressly confirmed by "The Winds of Winter" itself), so, at this point, there is very little evidence to suggest that it's going to be revealed that Rhaegar and Lyanna married in secret.

However, even if that does eventually end up being revealed as being the case, current information is rather clear when it comes to Jon's legal status: he's a Stark-Targaryen bastard, and this information should be stated plainly, clearly, and definitively in the article.
