It looks like their decision on an F-16 replacement has been pushed to the fall, to allow the formulation of a new National Defense Strategy (basically a budget white paper).

The competitors are the JSF, F/A-18, Gripen, and my guess is there are a number of reasons here, that they want more time to get firmer cost figures on the JSF, which seems to get more expensive daily, and see if they can afford it, and they see the the delay to extract price concessions.

I think that a lot of countries, like Denmark, which were likely JSF buyers, are looking at the numbers, and getting sticker shock.
