Some of you are speculating about the reason for the change. Here it is from the source:

In an interview with the Swedish design magazine Cap & Design, IKEA’s Ivana Hrdlickova says the main reason for the switch was to allow the company to use the same typeface in all countries (current IKEA typefaces do not contain Asian characters, for example). Being that Verdana was designed for the web, it also allows the company’s image to remain consistent online and in print.
